Frequently asked questions about COVID-19 vaccination

• The reason for a booster dose is to restore protection that may have decreased over time to a level that is no longer effective, in people who initially responded well to a “complete vaccine series”  

• This is different than a third dose which might be added to the standard “primary vaccine series” with the aim of enhancing the immune response and establishing an adequate level of protection for people who did not develop immunity or developed a sub-optimal immune response to a 2-dose primary series. 

• In short – a primary series for most healthy people remains 2-doses, and for these people, a third (booster) dose is offered to boost the immune system. A third-dose primary series is offered to those who are immunocompromised or vulnerable to ensure they have an adequate immune response and are protected. A fourth (booster) dose is then offered to this population to boost their immune response. 

• An mRNA COVID-19 vaccine, by Comirnaty (Pfizer-BioNtech) and Moderna, can be used for third doses and boosters in individuals 18 years of age and older. This is the recommendation whether you received AstraZeneca/COVISHIELD or an mRNA vaccine previously.
• While OPH offers both mRNA vaccines in its community clinics, several factors are considered when deciding what brand you will receive. You may not get to choose which mRNA brand you receive based clinical assessment and eligibility factors. Currently, and in accordance with guidance from the National Advisory Committee on Immunization.

• With many vaccinated individuals contracting COVID-19 due to the Omicron and BA.2 variants, it is reasonable to question the need for a booster dose, at this time.
• Two doses of vaccine are providing protection against severe illness due to the Omicron variant and far fewer individuals in Ontario are needing intensive care because of two-dose vaccination. However, a third, booster dose, is important to improve the immune response which may decrease over time since the last dose. The booster dose will also increase protection against serious illness and complications from COVID-19 including death.
• Fourth doses (second booster) are also available for eligible groups. A fourth dose will further improve the immune response, providing protection against serious illness and complication from COVID-19.  

• Those who have previously tested positive for COVID-19 should still be vaccinated with a third (booster) dose and people do not need COVID-19 testing prior to vaccination.
• Both National Advisory Committee on Immunization (NACI) and the Province recommend that individuals needing a booster dose who experienced COVID-19 infection after completing their primary series wait for three months after symptoms started or after testing positive (if no symptoms were experienced) before receiving a booster dose of COVID-19 vaccine; and for youth 12 to 17, provided it has been at least 184 days from completing the primary series
• For the purposes of COVID-19 vaccination, a previous COVID-19 infection includes individuals who received a positive COVID-19 test result (either a PCR or Rapid Antigen Test) or who was a household contact of a confirmed case and had COVID-19 symptoms.
• Individuals who have tested positive for COVID-19, or suspect having contracted it, should wait until they have recovered, completed the self-isolation period, and are feeling better before getting vaccinated. This will help to prevent exposing others at a vaccination clinic to the virus. 
• A third dose may be given earlier than three months (84 days) following infection so as long as 84 days have passed since the last dose of the primary series for individuals 18 years of age and older and 168 days since the last dose of the primary series for individuals 12 to 17 years of age.
• Informed consent should include that new evidence shows a longer interval between a COVID-19 infection and vaccination is associated with improved antibody response to COVID-19 vaccines.

Free parking options are available at each of the community clinic locations. 

Can I bring a support person with me to my appointment?

Yes, if you need help from a support person, they can attend the appointment with you. Staff will be on hand at the clinics to assist residents who arrive for their vaccinations. To reduce overcrowding at the clinics, we ask that you only bring one support person who is essential to you.

Are communication supports available on site?

Yes. Clinic staff can access interpretation services by telephone if needed. However, clients who wish to bring a support person with them to assist with interpretation at the clinic are welcome to do so. There is a limit of one support person per client.  

Residents who are eligible for vaccination are encouraged to make a transportation plan in advance of their appointment. This could include using public transit or asking a friend, family member or caregiver to provide a ride to your designated vaccination clinic.

There are several support services available to assist in getting to and from your appointment:

• Use the Travel Planner to plan your trip to any of the vaccine clinics located across the city.
• If you are a Para Transpo user, you can book your ride through the COVID-19 Vaccination Trip Reservation telephone line at 613-842-3600 between the hours of 10 am and 8 pm.
• If you are a resident age 65 years or older or an adult with disabilities you can request a ride through Ottawa Community Transportation after you have booked your appointment. Ottawa Community Transportation will contact you directly to confirm your transportation.

If you or someone you know requires transportation but do not have online access, please contact 211. A representative will assist in completing the online form on your behalf. Please have your vaccine booking confirmation number available when calling.

• If you are not eligible for support through Para Transpo or Ottawa Community Transportation, you can request a ride with a volunteer driver through the VaxAide online form, or by calling 613-869-8221.

• The treatment (Comirnaty/Pfizer-BioNtech) COVID-19 vaccine) and side effects
• Why it is recommended
• Risks and benefits if they get the vaccine, or do not get the vaccine

The individual giving the vaccination and the family must respect the young person’s decision about the vaccine. This means, it is possible your child could refuse the vaccine even if you wish them to have it. OPH recommends that parents and guardians discuss the COVID-19 vaccine with their eligible child(ren) before the vaccine appointment. The COVID-19 vaccine is voluntary.

If a child or youth is unable to consent for themselves, a substitute decision maker such as a parent or guardian, needs to provide consent.

A parent or guardian can attend a vaccine appointment with their child, however it is not required unless the child cannot consent for themselves or needs support. 

• Your booking confirmation code or email. Check your junk folder if you have trouble finding your email
• Your Ontario health card, if you have one. If you do not: a letter from your school, medical provider or faith leader with the child’s name, date of birth and address.
• Your immunization record, if available, to keep track of your COVID-19 vaccine
• An allergy form, if you have a suspected allergy to a COVID-19 vaccine or any of its ingredients or have had a previous allergic reaction to a vaccine
• A mask
• A support person, if needed. This could be your parent, or guardian or someone else that provides support

No, you are not currently mandated to disclose your child’s COVID-19 vaccination status or complete a Statement of Conscience or Religious Belief. The Statement of Conscience or Religious Belief applies to mandatory vaccines listed in the Immunization of School Pupils Act. Although the COVID-19 vaccine is highly recommended for those eligible, it is not currently mandated. Your child’s vaccination status may be requested by OPH as part of case and contact management if they have an exposure to determine their isolation requirements. Further guidance from OPH will be provided when contacted.

Can I get vaccinated at the same time as a family member and/or partner?

Individual appointments must be made for each person who is eligible for a vaccine.

How will I be notified when it's my turn to get the vaccine?

Residents of all ages who are not yet eligible for the vaccine are encouraged to follow announcements on the City of Ottawa and Ottawa Public Health websites and social media channels, and from your local news media to learn when they can receive their vaccine. You can also sign up for the City of Ottawa’s COVID-19 vaccination update e-subscription for regular news and updates on the vaccine roll-out.

Who is currently eligible for the COVID-19 vaccine?

The clinical trial data shows that there have been mild cases of myocarditis and or pericarditis reported after receiving the Novavax Nuvaxovid COVID-19 vaccine. According to the National Advisory Committee on Immunization (NACI), it is unclear whether these cases are indicative of a safety signal. Post-market safety surveillance, which is routinely done, is required to determine whether this is an adverse event of interest associated with Novavax Nuvaxovid. 

For more information see NACI Recommendations on the use of Novavax Nuvaxovid COVID-19 vaccine. 

Vaccination of specific populations

Yes. If you received one or more doses of a COVID-19 vaccine in one part of Ontario, you will be able to get your next dose in another city or town, if needed.

When you are registering for your next dose in the Provincial booking system, use the postal code of the address you will be at during the time of your appointment.

For example, if you received your first dose in Ottawa, but will be moving to Toronto for school in the fall when you are due for your second dose, use your new address when booking your dose.

If you have received one or more doses of a COVID-19 vaccine outside of the Province of Ontario, you may provide your proof of immunization to Ottawa Public Health. Complete the COVID-19 Out of Province Dose Documentation form to notify Ottawa Public Health of your out of province dose administration, and upload the documentation you have received.

Do not use this form to submit medical exemption information.

This form is to be completed by City of Ottawa residents only.

If you live outside of Ottawa, but within Ontario, contact your local public health unit to submit proof of your out of province vaccination.

If you are visiting Ottawa, you do not need to complete this form. If you are visiting from outside of Canada, please consult the Government of Canada's entry requirements.

If you received one or two doses of a COVID-19 vaccine series outside of Canada, that is not currently approved for use in Canada, you are eligible to receive an additional dose of a COVID-19 vaccine. You are also eligible to receive a booster dose three months (84 days) after your additional dose if you are 18 years of age and older or six months (168 days) after your additional dose if you are 12 years of age and older. Please visit a COVID-19 vaccination clinic to receive your COVID-19 vaccine that is approved for use in Canada. You may also be eligible to receive a second booster which is recommended five months (140 days) after your first booster. For more information and to determine if you are eligible for a second booster, see Who Can Receive their Fourth Dose? 

If you reside in Ottawa, please Complete the COVID-19 Out of Province Dose Documentation form to notify Ottawa Public Health of your out of province dose administration, and upload the documentation you have received.

I received three doses of a COVID-19 vaccine not approved for use in Canada, while outside of the country. Am I eligible to receive any other doses?

If you received three doses of a COVID-19 vaccine series outside of Canada, that is not currently approved for use in Canada, you are eligible to receive a booster dose. You can receive the booster dose three months (84 days) after your last dose if you are 18 years of age and older or 6 months (168 days) after your last dose if you are 12 years of age and older. Please visit a COVID-19 vaccination clinic to receive your COVID-19 vaccine that is approved for use in Canada.

You are also eligible to receive a second booster if you meet the eligibility criteria which is recommended 5 months (140 days) after your first booster. For more information, see Who Can Receive their Fourth Dose?

I received one or more doses of a COVID-19 vaccine through a Federal program while in the province of Ontario (for example military, global affairs or embassy vaccination clinic). How do I ensure my vaccination is recorded in Ontario?

What can I expect once I submit my proof of vaccination form?

You will receive an automatic confirmation email once you submit the Out-of-Province or Federal Documentation Form.

Once your submission is reviewed and approved by Ottawa Public Health you will receive an email with instructions on how to access your provincial vaccine receipt.

If your submission is not approved, you will receive an email from Ottawa Public Health with further instructions to re-submit with corrections and/or omissions.

I’m visiting Ontario, do I need to submit my proof of vaccination to be uploaded into the provincial system?

If you are visiting Ontario, please visit ontario.ca/covid19 for more information on what types of proof of vaccination you need.

If you are visiting from outside of Canada, please consult the Government of Canada's entry requirements.

The Out-of-province documentation form is to be completed by City of Ottawa residents only.

If you have confirmed that you are eligible to receive a vaccine but have a red and white Ontario health card, please call the Province of Ontario’s Provincial Vaccine Booking Line at 1-833-943-3900 (TTY 1-866-797-0007) to book your appointment. This line is available 8 am to 8 pm, 7 days a week. Information is available in more than 300 languages.

If you do not have a valid health card but are eligible for a vaccine, please call Ottawa Public Health at 613-691-5505 to book an appointment.

The National Advisory Committee on Immunization (NACI) has released  recommendations on the interchangeability of COVID-19 vaccines used in Canada as well as guidance on booster doses. This means that you could receive different vaccines for your doses.

NACI recommends that:

• If you received AstraZeneca/COVISHEILD as your first dose: you may receive either AstraZeneca/COVISHEILD vaccine or an mRNA vaccine, such as Comirnaty (Pfizer-BioNtech) or Moderna, for your second dose, unless contraindicated. However, an mRNA vaccine product is preferred.
• If you received an mRNA vaccine as your first dose: you should be offered the same mRNA vaccine for your second dose. If the same mRNA vaccine is not available or unknown, another mRNA vaccine can be considered interchangeable and should be offered to complete the vaccine series.
• An authorized mRNA COVID-19 vaccine, Comirnaty (Pfizer-BioNtech) and Moderna vaccines can be used for third doses and boosters in individuals 18 years of age and older. This is the recommendation whether you received AstraZeneca/ COVISHEILD or an mRNA vaccine previously. A booster dose of an authorized viral vector vaccine should only be considered when other authorized COVID-19 vaccines are contraindicated or inaccessible.

Whether you get the same vaccine or different vaccines for your doses (also called a “mixed schedule”), both are considered valid options. Both schedules will count as a full series. Consider talking to a healthcare professional for help in understanding information related to each vaccine, to help with informed decision-making on vaccination.

Something to note is that there is a possibility of increased short-term side effects with a mixed COVID-19 vaccine schedule. Common short-term side effects include headache, fatigue, muscle aches, joint pain and generally feeling ill. These side effects are temporary and should resolve on their own within 48 hours after vaccination.

If symptoms last or develop more than 48 hours after vaccination, or if symptoms continue or worsen for more than 48 hours after the first symptom(s) appeared, and you may have been exposed to COVID-19 in the previous 14 days, you should self-isolate and go for COVID-19 testing. If at any time symptoms are severe, seek medical assessment right away.

In regard to the booster/additional dose, NACI has outlined certain populations for which a specific product and/or doses may be preferred. See NACI’s Guidance on booster COVID-19 vaccine doses in Canada for additional rationale and considerations.

For more information on mixed vaccine schedules, please review NACI’s Interchangeability of Authorized COVID-19 Vaccines.

For information on how to book your vaccination appointment, please see COVID-19 vaccine information.

What about getting a third dose of the COVID-19 vaccine and my flu vaccine?

This year with the presence of COVID-19 circulating in the community, it is especially important for high risks groups to get the flu vaccine to reduce the potential risk of having COVID-19 and influenza at the same time.

The National Advisory Committee on Immunization (NACI) now recommends that COVID-19 vaccines may be given at the same time as, or before or after other vaccines. This includes live, non-live, adjuvanted, and non-adjuvanted vaccines. There are no specific safety concerns when routine vaccines are given at the same time or within days of each other. Please note that there could be stronger, temporary side effects when a COVID-19 vaccine and another vaccine are given at the same time or within days of each other.

NACI was previously recommending that COVID-19 vaccines be given at least 28 days before and 14 days after other vaccines. However, after reviewing the evidence available on COVID-19 vaccines and the data and experience of giving other routine vaccines at the same time or within days of each other, NACI has since changed their recommendation.

There are four COVID-19 vaccines currently approved for use in Canada. 

All four vaccines are safe and effective against symptomatic COVID-19 infection and protect you from severe COVID-19 illness and hospitalization. COVID-19 vaccines work best when immunizing those at highest risk of severe illness first, which helps protect each other and helps prevent hospitals from being overwhelmed from COVID-19 cases.

No vaccine is perfect, and there is a chance that you may still get COVID-19 after being vaccinated. Vaccines take time to work, and vaccine effectiveness against novel variants is still being investigated. It is very important to continue following public health measures such as physical distancing, wearing a mask, minimizing contact with people outside of your household, washing your hands often, and staying home if you are sick. Healthcare and other staff must still wear personal protective equipment (PPE) even after they have been vaccinated.

Vaccine efficacy is a representation of how well a vaccine will work at preventing illness caused by a particular virus.   In clinical trials, vaccine efficacy (VE) or effectiveness is interpreted as the proportionate reduction in disease among the vaccinated group. A VE of 50% indicates a 50% reduction in disease occurrence among the vaccinated group, or a 50% reduction from the number of cases you would expect if they have not been vaccinated. In a group of 100 vaccinated people, on average, only 50 people instead of all 100 people would get ill if all 100 were exposed to the virus.

It is important to note that all of the COVID-19 vaccines currently approved are effective at reducing the risk of serious illness, hospitalization, and death, and will help control the spread of COVID-19 in the community. A 50% reduction in disease occurrence could still play an important role in ending an epidemic. 

The AstraZeneca and Janssen COVID-19 vaccines are non-replicating viral vector-based vaccines. 

Viral vector-based vaccines use a virus, which has been modified to be harmless, as a delivery system to build your immunity. When injected into the body, these COVID-19 vaccines produce a surface protein from the SARS-CoV-2 virus, specifically the SARS-CoV-2 spike protein. The spike protein does not make you sick -- it helps your body develop a strong immune response without exposing you to the virus that causes COVID-19. Many people around the world have safely received viral vector vaccines for COVID-19.

American Sign Language - How do mRNA vaccines work?

These types of COVID-19 vaccines use messenger RNA (mRNA). mRNA provide instructions to the cells in our bodies to make a viral protein from the coronavirus called a “spike protein”. The mRNA provides the instructions that allows the cell to make the spike protein, and then the immune system is activated to recognize the spike protein as being different from the body’s own proteins which initiates an immune response. The mRNA is then degraded by normal cellular mechanisms and the spike proteins are destroyed by the immune system. mRNA vaccines are just one of the different types of vaccines currently used to prevent COVID-19 disease caused by the SARS-CoV-2 virus. COVID-19 vaccination along with public health measures will offer the best protection from COVID-19.

How is the COVID-19 vaccine different from the influenza (flu) vaccine?

The COVID-19 and influenza vaccines are separate products. The COVID-19 vaccine will not protect you against influenza. The seasonal influenza vaccine changes every flu season. When you receive your annual flu vaccine, you are protected only from the specific influenza strains that are circulating for that given season that are covered by the vaccine.

The flu vaccine won’t protect you against COVID-19.

COVID-19 vaccination (including booster dose) is strongly recommended during pregnancy. Getting vaccinated, as soon as possible, is the safest choice to protect yourself and your baby from the known risks of COVID-19 infection.

The National Advisory Committee on Immunization (NACI) recommends you get a complete series with an mRNA COVID-19 vaccine if you're pregnant or breastfeeding. Getting the COVID-19 vaccine can prevent serious illness, hospitalization, and complications from COVID-19 infection.

In Ontario, all pregnant individuals are eligible and prioritized to be vaccinated as soon as possible, at any stage of pregnancy. The same applies to receiving a booster dose three months after their last dose.

COVID-19 vaccines are very effective in protecting you from severe illness.

• Getting the vaccine can help prevent complications or bad outcomes for parent and baby. Like everyone else, most pregnant people have mild COVID-19. However, pregnant people are at an increased risk of severe illness requiring hospital care and admission to the intensive care unit compared to those who are not pregnant.
• Giving birth too early in pregnancy (preterm birth), having a caesarean delivery and having a baby admitted into a neonatal intensive care unit is more common in pregnant people with severe COVID-19.

There is growing evidence about the safety of COVID-19 vaccines in pregnancy.

• The mRNA vaccines are effective at reducing the risk of a COVID-19 vaccine infection caused by any variant of the virus (e.g. Omicron) similarly in both pregnant and non-pregnant people. These vaccines do not contain live virus.
• Booster doses decrease the chance of having a symptomatic COVID-19 infection, the severity of the COVID-19 illness and the chance of being hospitalized for COVID-19.
• Antibodies created by the COVID-19 vaccine can offer protection to your baby and are passed through the placenta and/or in your breastmilk.

The mRNA COVID-19 vaccines and booster doses are safe in pregnancy.

• Several studies with large numbers of pregnant people have shown that vaccination immediately before and/or during any time in pregnancy has no impact on pregnancy outcomes.
  • No increased risk of miscarriage, preterm birth, stillbirth, growth restriction, high blood pressure during pregnancy, medical complications of pregnancy or death.

Pregnant and breastfeeding individuals who receive the mRNA (Comirnaty/Pfizer-BioNtech or Moderna) vaccines experience the same side effects of vaccination as non-pregnant individuals.

Evidence about the safety and effectiveness of COVID-19 vaccination during pregnancy, has been growing from real-world use. The data shows that mRNA COVID-19 vaccines are safe for people who are pregnant or breastfeeding. No safety concerns were identified in a study of more than 35,000 pregnant people who received an mRNA COVID-19 vaccine within 30 days of conception.

The mRNA COVID-19 vaccines:

• Do not contain any live virus.
• Do not contain any mercury, aluminum, formaldehyde, or substances harmful to you and/or your baby.
• Do not contain any human and/or animal blood or by-product(s).
• Cannot be measures in your bloodstream; thus, the baby is not exposed to the vaccine.

Anyone getting the vaccine may have some side effects.

• Common side effects after receiving the COVID-19 vaccine are pain at the injection site, fatigue, headache, and muscle pain. This is caused by the immune system’s normal response to the vaccine. These side effects are generally not serious and go away on their own.
• In more than 35,000 pregnant and/or breastfeeding people who were monitored at the time of COVID-19 vaccination, less than 10% of pregnant people experience a fever.
  • Talk to your doctor or midwife if you develop a fever, or any side effects that worry you or that last more than 3 days, so they can give you advice. A high fever that lasts too long during the first three months of pregnancy (first trimester) may increase the risk of miscarriage or abnormalities to the baby.
• As with any vaccine, allergic reactions, including anaphylaxis, are rare but can occur. Talk to your health care provider if you have allergies to medications.

The National Advisory Committee on Immunization (NACI) strongly recommends that a complete vaccine series with an mRNA COVID-19 vaccine should be offered to people in the authorized age group who are pregnant or breastfeeding. Booster doses are also recommended for pregnant or breastfeeding people.

The Society of Obstetricians and Gynaecologists of Canada (SOGC) recommends that all individuals who are pregnant or those trying to become pregnant should receive all COVID-19 vaccination doses, including the booster dose, when eligible.

Speak to your health care provider about getting the COVID-19 vaccine when pregnant or breastfeeding. If you decide to get the COVID-19 vaccine and need another vaccine around the same time, your health care provider will help you determine the appropriate time between different vaccines. 

Make sure you understand as much as you can about COVID-19, vaccines, and boosters. Ask a trusted source, such as your obstetrician, midwife, family doctor or nurse, any questions. 

The risk of COVID-19 is higher if:

• The dominant variant circulating (i.e., Omicron) is more easily passed from person-to-person.
• You live in a community with a lot of COVID-19 cases
• You have regular contact with people outside your home
• You live in a crowded housing situation
• You, or another member of your household, work in a high-risk environment (for example, you are a front-line essential worker or a healthcare worker)

The risk of developing severe illness from COVID-19 in pregnancy is higher if:

• You have medical problems such as pre-pregnancy diabetes, pre-pregnancy high blood pressure, a compromised immune system, kidney disease, liver disease, heart disease, or asthma
• You are overweight
• You smoke
• You are 35 years of age or older
• You are in the last three months (third trimester) of your pregnancy

It’s safer to get vaccinated (and boosted) as soon as possible, especially if you are at an even higher risk of getting COVID-19 and developing severe illness. The known risks of severe illness from COVID-19 are greater than the known risks of the vaccine.

If you choose to wait, you need to know that without the vaccine, you are at higher risk of severe illness from COVID-19.

If you are pregnant or become pregnant soon after getting the first or second dose of the vaccine, you should complete the full series and receive your booster dose.

Several studies show that prior to and in the first trimester, there is no impact of COVID-19 vaccination on the risk of miscarriage or any adverse pregnancy outcome.

There is no evidence to suggest that COVID-19 vaccines have any effect on your fertility or chances of becoming pregnant. Fertility treatment is not a medical reason that prevents you from getting vaccinated. 

Vaccination is one of the most effective ways to prevent the spread and reduce the impact of infectious diseases, whether it is the seasonal flu (influenza) or childhood infections such as chickenpox (varicella). Safe and effective vaccines for COVID-19 are now available to protect us against COVID-19. While many people infected with COVID-19 experience only mild illness, others may get a severe illness or even die. There is no way to know how COVID-19 will affect you, even if you are not at increased risk of severe complications. 

The COVID-19 vaccine has been shown to:

• Help protect you by creating an antibody response without having to experience the illness of COVID-19, reducing your risk of getting COVID-19.
• Reduce your risk of severe illness or death if you do get COVID-19.
• Reduce your risk of spreading the virus that causes COVID-19 to others.

Also, the more people are vaccinated in the community, the less the risk of the virus replicating, mutating, and possibly coming more resistant to vaccines.

Why I am choosing the vaccine

Why I am choosing the vaccine videos are available in French, Arabic, Mandarin, and Somali. 

Community immunity is reached when enough people have protection against a disease, which makes it unlikely that a virus or bacteria can spread and cause more infections. This protection can be either from a previous infection or vaccination. As a result,  the whole population within the community is protected. But those who are not protected because they have never had the disease, did not get vaccinated or the vaccine was not as effective for them can still get sick. This is why it is not a good idea to rely on community immunity to protect yourself instead of getting vaccinated.

The percentage of people who need to have protection to reach community immunity varies by disease. 

Some estimates for COVID-19 suggest it may be near 60 to 70%. However, community immunity calculations may not be reliable in the context of COVID-19 because of many unknowns. The effectiveness of COVID-19 vaccines in preventing asymptomatic infection remains unknown right now. For this reason, community immunity calculations will only give an estimated target for vaccination programs.

Until the effects of the COVID-19 vaccines have been fully studied, it is best to not assume that vaccinations will protect others. We must continue to protect ourselves and others by:

• wearing a mask
• practicing physical distancing
• practicing hand hygiene
• staying home and getting tested when sick

These measures will help to continue to stop the spread of COVID-19.

Feeling worried or hesitant is completely normal when something is new. Vaccination is a personal choice, and one that most Canadians agree is an important part of maintaining good health and for disease prevention.

Need more information? Having questions about the vaccine is totally normal. Learn more at our frequently asked questions about COVID-19 vaccines. 

Will the current COVID-19 vaccines protect against new variants of COVID-19?

The evidence we have now suggests that current vaccines may be effective or partially effective against one or more variants. But more data is still needed. Vaccine makers are looking into how vaccines can be changed to keep them effective against new variants.

Non-variant SARS-CoV2 continues to cause severe illness. This is preventable through vaccination. 

No. None of the COVID-19 vaccines currently approved for use in Canada use the live virus that causes COVID-19. There are several different types of vaccines in development. The goal of each of the vaccines is to teach the immune system how to recognize and fight the virus that causes COVID-19. Sometimes this process can cause symptoms, such as fever. These symptoms are normal and are a sign of the immune response to vaccine.

It usually takes the body a few weeks to build immunity after receiving a vaccine. It is possible that someone could become infected with the COVID-19 virus before or just after getting the vaccine and get sick. This happens because the vaccine has not had enough time to provide protection in the body. Learn more about COVID-19.

Many companies are making vaccines and the COVID-19 vaccines that are approved in Canada are from Comirnaty (Pfizer-BioNtech), Moderna, AstraZeneca and Janssen do not contain gelatin or pork products.

Vaccines that may become available later may include gelatin or pork products and as more information becomes available for these, consult with religious leaders about which specific vaccines are recommended. It is important to know there are approved vaccines in Canada that do not contain gelatin or pork products.

Is it true that the COVID-19 vaccines contain elements from a human fetus?

No. Many researchers use what are called ‘cell lines’ to develop vaccines. Cell lines are cultures of human or animal cells that can be grown in a lab for long periods of time. Most cells will eventually stop dividing and die, but some cell lines, called immortal cell lines, never stop dividing. These cell lines are especially useful for vaccine work. The viral-vector vaccines currently approved for use in Canada were produced using cell lines from human embryos that were electively aborted many years ago*. Scientists used these cell lines to grow the harmless virus needed to create an immune response against COVID-19. Cell lines from elective abortions are called fetal cell lines. Fetal cell lines have been used in medicine for years. Many of the vaccines that are widely used today were developed using fetal cell lines. These include some of the vaccines used to prevent rubella, hepatitis A and chickenpox. Although human cell cultures may have been used in the process of developing these vaccines, the vaccines do not contain any human cells or tissue.

Each of the COVID-19 vaccines being used in Canada have been approved and are safe and effective.

*The viral vector vaccines (AstraZeneca and Janssen) used fetal cell lines in the production of the final vaccine product. The mRNA vaccines (Comirnaty/Pfizer-BioNtech and Moderna), used fetal cell lines in the research phase but not in the production:

• AstraZeneca uses the HEK-293 cell line for the development, testing and production of the vaccine.
• Janssen (J&J) uses PER.c6 cell line for the development, testing and production of the vaccine. This cell line was developed from retinal cells of an 18-week-old fetus aborted in 1985.
• Comirnaty (Pfizer-BioNtech) was developed using genetic sequencing on computers without fetal cells. The HEK-293 abortion-related cell line was used in research related to the vaccine. It was not used for testing or the ongoing production.
• Moderna does not need aborted fetal cell lines for production. But, aborted fetal cell line was used in both development and testing in the initial stage.

Can someone who has been vaccinated ‘shed the virus’ and put others at risk?

Vaccinated people do not shed any virus because the vaccines do not contain whole, living viruses. The vaccines also do not cause whole viruses to be created. The current vaccines approved for use in Canada do not contain live SARS-CoV-2 virus.

There are two classes of approved COVID-19 vaccines in Canada: mRNA vaccines, and viral vector-based vaccines.

mRNA vaccines

Both mRNA vaccines approved for use in Canada ( Comirnaty/Pfizer-BioNtech and Moderna) use synthetic mRNA. Synthetic mRNA is made to contain instructions for the spike protein found on the coronavirus. Once given to someone, the mRNA is delivered to the vaccinated person’s cells. The cell uses this to make copies of this spike protein, not whole viruses, which allow the body’s immune system to recognize and fight the coronavirus.

Viral vector-based vaccines

The COVID-19 viral vector-based vaccines (AstraZeneca and Janssen) use a harmless, weakened adenovirus as a vector (a shell). When the vaccine is made, DNA coding for the SARS-CoV-2 spike protein is put into this adenoviral vector (or shell). The vector acts as a delivery system to bring the SARS-CoV-2 spike protein code to human cells. The vector (not SARS-CoV-2) will enter a cell in the body to deliver the instructions. Then the instructions from inside the vector use the cell’s machinery to produce the spike protein and bring it to the surface of the cell. A vaccinated person’s immune system will recognize that the protein doesn’t belong there and train the body’s immune system to attack the coronavirus in the future. However, the spike protein doesn’t infect the recipient with SARS-CoV-2. It cannot cause the infection because it is not a whole virus.

Both mRNA COVID-19 and viral vector-based vaccines cannot cause infection with SARS-CoV-2, and therefore cannot cause viral shedding of SARS-CoV-2.

No. While experts learn more about the protection that COVID-19 vaccines provide under real-life conditions, it will be important for everyone to continue practicing public health measures to help stop the spread of COVID-19. That means covering your mouth and nose with a mask, washing hands often and never touching your eyes, nose or mouth with unwashed hands, staying at least two metres (six feet) away from others and self-isolating when sick.  

Now that I am up to date and received all recommended COVID-19 vaccine doses, including any booster dose(s), am I able to have more contact with others, like my family and friends? (can I go see my grandchildren, gather with friends etc.?)

Please refer to Ottawa Public Health’s Be Social Wise webpage for specific guidance on gathering with your loved ones.   

Why would I want to get the COVID-19 vaccine if we are still required to follow public health measures even after vaccination?

The main reason to get vaccinated is to protect your own health. Vaccines add a valuable layer of protection against COVID-19 infection which can lead to severe illness and death. More people vaccinated means fewer COVID-19 infections in the community. This is important in helping to reduce the burden on the health care system. This would mean less people in the hospital, less patients in ICU and more capacity for hospitals to resume surgeries and treatments. 

At this time, we do know that getting the vaccine prevents people from getting seriously ill from COVID-19, but that they could still pass it on to others. What we have learned from other vaccines is when more people are vaccinated and immune, this should eventually mean a higher likelihood of indirect protection to those who are not immune to the disease.  

How long can we expect public health measures to be in place after COVID-19 vaccination in the community?

It is not known at this time. As we know public health measures such as mask wearing, physical distancing and hand washing help to limit the spread of COVID-19. Individual public health measures  will be strongly recommended for as long as they are needed. Measures in place at businesses and schools could be lifted over time depending on levels of community transmission.

Mask requirements when returning from international travel

A reminder that under current federal travel requirements, upon return from international travel, individuals that are exempt from quarantine, AND that are not fully vaccinated must wear a mask at all times when in public spaces (including schools and child care), for their first 14 days in Canada. Fully vaccinated returning international travelers are no longer required to mask in public settings for 14 days after arrival to Canada.

Important: The travel guidelines are set by the federal government and are continuously changing. Please check for current federal information at the link above and direct any questions to the federal COVID-19 information line at 1-833-784-4391 or phac.covid19.aspc@canada.ca. 

What are the requirements regarding proof of vaccination to enter Canada?

Can I travel after being vaccinated with a full series of a COVID-19 vaccine? What If I have a mixed dose schedule?

It is important to assess your own personal risk factors for travel. It is also important to be aware of the COVID-19 situation occurring at your travel location. Please check with the country you are travelling to for vaccine, testing, isolation and other public health recommendations. 

If you have a mixed dose series, please know that you are well protected from a COVID-19 infection. Mixed dose schedules continue to be safe and effective. With regards to travel and other countries, it is important to check with the country you are travelling to for their requirements.

Can getting a COVID-19 vaccine affect menstruation or fertility?

It is not clear if the COVID-19 vaccine can affect your periods. But getting sick with COVID-19 can affect your periods. There was a  study done in Wuhan, China (Chen et al., 2020). It showed that one fifth of patients with confirmed COVID-19 had temporary changes in:

• the length of their menstrual cycle; and
• the amount of their bleeding.

Fertility, the ability to get pregnant, is not affected by vaccines. During the years that someone could get pregnant, precaution should be taken with certain live virus vaccines. This is because of theoretical risk to the fetus, not because fertility could be affected. An example of a live virus vaccine is the measles vaccine. 

The COVID-19 vaccines in use are not live virus vaccines. There is no biological reason to believe that the current COVID-19 vaccines would impact someone’s fertility. The U.S. has safety data of over 35,000 pregnant women who received COVID-19 vaccine. This data has not identified any safety concerns with getting an mRNA vaccine within 30 days of conception. NACI has recommended that you do not need to avoid pregnancy after vaccination with an mRNA vaccine. 

Male fertility: millions of men worldwide have received the COVID-19 vaccines. There is no evidence to date that shows that getting a COVID-19 vaccine could lead to fertility loss. We do know that all vaccines, including the COVID-19 vaccines, can cause a brief fever in some people. Significant fever from any cause (e.g., if you get the flu) may have a temporary impact on sperm count and quality. But, this effect is only temporary. Some studies have shown that if you get COVID-19, it may affect the quality of your sperm. It is unclear how long this effect lasts.  

Studies of COVID-19 vaccines have shown that they are very effective at preventing people from becoming sick with COVID-19. However, right now we do not have enough information to show us how likely it is that someone who has been given a COVID-19 vaccine can develop an asymptomatic (no symptoms) COVID-19 infection and pass it to others.  

While there is early evidence suggesting that the vaccine may also reduce COVID-19 transmission, NACI is recommending that everyone continue to practice public health measures (e.g. wearing a face mask and physical distancing) regardless of whether or not they received a COVID-19 vaccine. More information on the vaccine’s ability to reduce COVID-19 transmission is expected in the near future.  

This means the vaccines will protect those who receive it from getting sick, but it is possible that someone who has been vaccinated could still carry the virus pass the virus on to others, although it would likely be at a much lower rate.  

The reason the COVID-19 vaccine was approved quickly is not because safety standards have changed, it’s because Health Canada shortened the administrative and organizational process of vaccine authorization. The safety requirements in clinical trials for the COVID-19 vaccine were just as strict as the regular process for any other vaccine.

Vaccines add an extra layer of protection. Most vaccines decrease the circulation and transmission of the diseases against which they provide immunity. However, we still need more real-life data about how the COVID-19 vaccines will impact transmission of COVID-19. For now, it is very important that we continue to follow public health measures to keep each other safe.

All vaccines are reviewed by Health Canada and the National Advisory Committee on Immunization (NACI). They determine who the vaccines are safe and effective for. The Comirnaty (Pfizer-BioNtech) vaccine is currently approved for individuals born in 2016 or earlier.

Due to lack of evidence, children born before 2016 are not currently eligible for the COVID-19 vaccines. There are vaccine companies that are now studying the vaccine in younger age groups. Health Canada and NACI will review new evidence on vaccine safety and effectiveness. They will use the emerging evidence to update their recommendations.

Yes, it is safe to take the vaccine as long as you are feeling well on the day you are to have your vaccine. You do not need a COVID test in order to get the vaccine. However, it is still important to screen yourself before being vaccinated. Public health measures are in place at clinics to keep you and others safe. Please wear a mask, distance yourself from others and stay home if you or anyone in your household is ill. 

Is it safe for seniors or other high risk groups to go to public vaccination clinics?

Yes. Measures are being taken at vaccine clinics to make sure that the public is safe. It is important that if you are going to get vaccinated, that you screen yourself for COVID-19 first. If you or anyone in your household is not well, or has symptoms of COVID-19, you must stay home.

Vaccine clinics are set up to be as safe as possible. The setup of each clinic will allow for physical distancing.  There will also be a limit on the number of people in a space at one time. Everyone is required to wear a mask while attending a clinic. Staff giving the vaccine will also be wearing Personal Protective Equipment (PPE).

Please note that after getting your vaccine, you will need to stay and sit in the clinic for at least 15 minutes. If you need support during your clinic visit, you can bring a support person with you. 

Symptoms include:

• Shortness of breath
• Chest pain
• Leg swelling
• Persistent abdominal pain
• Neurological symptoms including sudden onset of severe or persistent worsening headaches or blurred vision
• Skin bruising (other than at the site of vaccination) or petechiae

Can I still get a vaccine at a clinic if I have a history of fainting when getting a needle?

Yes. Please let your immunizer at the clinic know that you have a history of fainting during or after getting a vaccine. You will be accommodated by being given your vaccine lying down on a mat. There is an area of the clinic that Is screened off for privacy.

Fainting after a vaccine is not an adverse reaction and can happen to people for different reasons including stress or anxiety.

Please note: the FAQ above refers to fainting only, not a more a severe allergic reaction, such as anaphylaxis. Please be sure to tell your immunization provider if have a history or fainting or a history of severe allergic reactions following vaccination.

What do I do if I or someone I support has a needle phobia or fear but would still like to get a COVID-19 vaccine at a clinic?

You never know how COVID-19 will affect your health after the acute illness has passed. Most people with COVID-19 get better in a few weeks. Some take longer to recover or have problems during recovery. 

Anyone can experience post-COVID-19 health conditions (also referred to as long COVID, long-haul COVID, post-acute COVID-19, long-term effects of COVID, or chronic COVID). This includes people who did not have symptoms while they had COVID-19. Every person is different. 

Anyone can experience post-COVID-19 health conditions (also referred to as long COVID, long-haul COVID, post-acute COVID-19, long-term effects of COVID, or chronic COVID). This includes people who did not have symptoms while they had COVID-19. Every person is different.  

Preventing post-COVID conditions / ‘long-COVID’:  

According to the Centers for Disease Control and Prevention (CDC), the best way to prevent post-COVID conditions is to protect yourself and others from being infected. For those who are eligible, getting vaccinated against COVID-19 can help prevent infection and protect against severe illness. The CDC also states that research shows those who are vaccinated and become infected with COVID-19 are less likely to report post-COVID conditions compared to those who are not vaccinated.

Symptoms of post-COVID-19 health conditions can be new or ongoing and last weeks or months following a COVID-19 infection. Some of these symptoms can include:

• Difficulty breathing or shortness of breath
• Tiredness or fatigue
• Difficulty thinking or concentrating (sometimes referred to as “brain fog”)
• Cough
• Chest or stomach pain
• Headache 

Post-COVID-19 health conditions appear to be less common in children and adolescents. Symptoms in children and adolescents are similar to those experienced by adults. 

The causes and treatments for each person who has longer-term health problems will be different. The long-term effects of COVID-19 infection are still being studied. Have a discussion with your health care provider about your personal situation if you are having problems during your recovery. 

For more information on post-COVID-19 health conditions, please visit:

• Post-COVID Conditions | CDC 
• Post-COVID-19 condition - Canada.ca

No. People with a history of severe allergic reaction to a component of the COVID-19 vaccine should not receive the vaccine. 

Visit the Health Canada web page to learn who should not received the  Comirnaty (Pfizer-BioNtech)-BioNTech, Moderna, AstraZeneca and Janssen COVID-19 vaccines.

American Sign Language - What are the side effects of the COVID-19 vaccines?

The most frequent side effects are injection site pain, fatigue and headache. Some people who got the vaccine in trials also reported muscle pain, chills, joint pain and fever. These symptoms were usually mild or moderate and went away within a few days. These are all expected reactions to vaccines because of the immune response. They are very similar to those reported following the seasonal influenza vaccination.

You can find more information on the side effects for each vaccine here: Comirnaty (Pfizer-BioNtech), Moderna, AstraZeneca or Janssen.

No serious safety concerns have been causally linked to COVID-19 vaccines approved in Canada.

If someone experiences an adverse event following immunization, they should report it to a healthcare professional (e.g., family doctor).

An adverse event following immunization (AEFI) is an unwanted or unexpected health effect that happens after someone receives a vaccine, which may or may not be caused by the vaccine.

Public health surveillance of AEFIs is important for timely detection of rare vaccine safety issues. For more information visit the OPH page on AEFI reporting.

Expected side effects for each vaccine product are listed on the vaccine product monograph; common side effects could be found under ‘Side effects and risks’.

Healthcare professionals should complete the Adverse Events Following Immunization (AEFI) Form and send it to the local public health unit.

New Online Reporting Option for AEFIs

We are pleased to announce an online portal for submitting AEFI reporting securely in PDF format: https://secureforms.ottawapublichealth.ca/vaccines/AEFI-Submission-EN

This provides an another option, in addition to reporting by fax to: 613-580-9660

If I receive the COVID-19 vaccine and experience symptoms afterwards that are similar to COVID-19, do I need to self-isolate/get tested?

Can I get the COVID-19 vaccine if I recently got another vaccine or if I am due for another vaccine?

The National Advisory Committee on Immunization (NACI) was previously recommending that COVID-19 vaccines be given at least 28 days before and 14 days after other vaccines. However, after reviewing the evidence available on COVID-19 vaccines and the data and experience of giving other routine vaccines at the same time or within days of each other, NACI has changed their recommendation.  NACI now recommends that COVID-19 vaccines may be given at the same time as, or before or after other vaccines. This includes live, non-live, adjuvanted, and non-adjuvanted vaccines. There are no specific safety concerns when routine vaccines are given at the same time or within days of each other. Please note that there could be stronger, temporary side effects when a COVID-19 vaccine and another vaccine are given at the same time or within days of each other.

What should I consider before receiving the vaccine? 

• Wait to get vaccinated if you have a fever or are sick with COVID-19 symptoms. This will help avoid confusing symptoms from other illnesses with vaccine-related adverse events. It also helps to decrease COVID-19 transmission at an immunization clinic
• Are you on long-term anticoagulation therapy? National Advisory Committee on Immunization (NACI) recommendations support that most people can be safely immunized without stopping their anticoagulation (blood thinner) therapy
• If you have a bleeding disorder, NACI recommends that you make sure it is well managed before immunization

• Do you have allergies? The Public Health Agency of Canada (PHAC) recommends that people with a history of serious allergies speak to their healthcare provider before getting a COVID-19 vaccine.
• The Canadian Society of Allergy and Clinical Immunology (CSACI) has a page of COVID-19 Vaccines FAQs which may be helpful (only English version available).
• For a technical discussion of anaphylaxis and allergies, please see contraindications and precautions from the National Advisory Committee on Immunization’s Recommendations on the use of COVID-19 vaccines.

Can I get vaccinated if I am immunocompromised and or have an autoimmune condition?

Can the medications I take interfere with the effectiveness of the vaccines? Can they cause other side effects after vaccination?

You should talk to your health care provider if you:

• have an autoimmune condition;
• are receiving immunosuppressing therapies; and
• have other specific medical conditions.

Your health care provider may have recommendations about the timing of your COVID-19 vaccine in relation to:

• other vaccines, or
• treatment for autoimmune or immunocompromising conditions.

Before being vaccinated you will be asked some screening questions. You can find these questions here: COVID-19 Vaccine Screening and Consent Form.

Health care providers can find more information here:

• NACI recommendations, and
• Ontario Ministry of Health recommendations on vaccinations for special populations 

The NACI recommendations are updated as new information becomes available. They have sections with information on:

• “Drug interactions”; and
• “Blood products, human immunoglobulin and timing of immunization”.

Have the vaccines been tested on people with a variety of rare conditions?

People who are immunosuppressed may have been excluded from clinical trials for COVID-19 vaccines. People with rare conditions may not be adequately represented in clinical trials for COVID-19 vaccines.

In general, non-live vaccines can be given to individuals who are immunosuppressed.  No safety issues  of concern have been noted to date in the worldwide use of these vaccine products. The vaccines have been tested on thousands of diverse people in many countries before being approved. This is in order to have a good cross-section of society.

Vaccine manufacturing companies report information from clinical trials. This information includes medical conditions of the people who participated. You can view information from clinical COVID-19 vaccine trials. This is a database of privately and publicly funded clinical studies done around the world.

If you have a medical condition, please talk to your health care provider for things to consider. 

You cannot book through the provincial portal. Booking will be through your local public health unit. Use this online form to register for a Janssen (Johnson & Johnson) COVID-19 vaccine.

Viral vector-based vaccines use a virus, which has been modified to be harmless, as a delivery system to build your immunity. When injected into the body, these COVID-19 vaccines produce a surface protein from the SARS-CoV-2 virus, specifically the SARS-CoV-2 spike protein. The spike protein does not make you sick -- it helps your body develop a strong immune response without exposing you to the virus that causes COVID-19.

Messenger RNA (mRNA) vaccines provide instructions to the cells in our bodies to make a viral protein from the coronavirus called a “spike protein”. The mRNA provides instructions that allows the cell to make the spike protein, and then the immune system is activated to recognize the spike protein as being different from the body’s own proteins which initiates an immune response. The mRNA is then degraded by normal cellular mechanisms and the spike proteins are destroyed by the immune system. mRNA vaccines are just one of the different types of vaccines currently used to prevent COVID-19 disease caused by the SARS-CoV-2 virus. COVID-19 vaccination along with public health measures will offer the best protection from COVID-19.

The mRNA vaccines remain the recommended vaccines to offer to eligible individuals. Those 18 years of age or older can receive the Janssen as their COVID-19 vaccine if they meet any of the following criteria:

• Have not had any doses of a COVID-19 Vaccine, because of a known allergy to one or more of the components of a mRNA COVID-19 Vaccine.
• Have not received any COVID-19 vaccine and declines an mRNA vaccine (i.e., is looking for an alternative to the mRNA vaccine).
• Have had a serious Adverse Event Following Immunization (AEFI) after a dose of mRNA COVID-19 vaccine and have been advised by an appropriate Physician or Nurse Practitioner to receive a non mRNA COVID-19 vaccine for future doses.

Please note that individuals who received AstraZeneca as their first dose of COVID-19 vaccine, and do not have a contraindication to receiving an mRNA COVID-19 vaccine are not eligible to receive the Janssen vaccine and should receive an mRNA COVID-19 vaccine.

• Who are younger than 18 years of age
• Who have experienced major venous and/or arterial thrombosis with thrombocytopenia following vaccination with any vaccine
• Who have a history of capillary leak syndrome (CLS)
• Who have experienced a previous cerebral venous sinus thrombosis (CVST) with thrombocytopenia
• Who have experienced heparin-induced thrombocytopenia (HIT)
• Actively receiving monoclonal antibody therapy OR convalescent plasma therapy for the treatment or prevention of COVID-19
  • Vaccine should not be administered while actively receiving therapy

• Headache
• Nausea
• Muscle Pain
• Pain at injection site
• Fatigue
• Fever

The COVID-19 situation can be very stressful. It is OK to not be OK.
