Immunizations

On this page:

Immunization through vaccination, is a public health initiative to prevent illness, disability and death from vaccine preventable diseases. High immunization coverage is essential for the effective prevention and control of vaccine preventable diseases (e.g., measles, mumps, rubella, diphtheria, tetanus, polio).

Vaccinations are provided as part of publicly funded health care in Ontario. Ontario has an annual universal influenza immunization program to offer vaccination against seasonal influenza. In addition, vaccines against common serogroups of invasive meningococcal disease, invasive Streptococcus pneumoniae and Haemophilis influenza are part of the publicly funded immunization schedule.

COVID-19 Vaccinations 

COVID-19 Vaccinations Dashboard 

Ottawa Public Health’s COVID-19 Vaccination Dashboard provides up-to-date information on COVID-19 vaccinations in Ottawa. Data in this dashboard are based on information extracted from the provincial system COVax-ON. This is a dynamic system that allows for ongoing updates; data represents a snapshot at the time of extraction and may differ from previous or subsequent dashboard updates.

COVID-19 Vaccinations Open Data 

 
Archived COVID-19 Vaccinations by ONS Neighbourhood 

We want to ensure that every single community in Ottawa is protected against COVID-19. To this end, we are working to ensure everyone has access to vaccines.

Following the implementation of mass-vaccination against COVID-19 in Canada, Ottawa Public Health (OPH) partnered with the Ottawa Neighbourhood Study (ONS) to map neighbourhood-level COVID-19 vaccination rates. This now archived map, last updated in November of 2022, provided a snapshot of COVID-19 vaccination across Ottawa, based on ONS neighbourhoods.

Disparities in vaccine rates across neighbourhoods were observed and using these data, OPH worked with community partners including the health care sector to address inequities in accessing the COVID-19 vaccine. OPH and partners developed tailored options for specific neighbourhoods to ensure that anyone who wanted the vaccine could get it.

To access these data, please go to the archived COVID-19 Vaccination by ONS Neighbourhood Dashboard on the Ottawa Neighbourhood Study website.

Routine Childhood Immunizations  

For children and youth there are nine diseases (diphtheria, tetanus, polio, pertussis, meningococcal disease, measles, mumps, rubella, and varicella) for which vaccination coverage is required to attend school in Ontario under the Immunization of School Pupils Act (ISPA). ISPA-required immunizations are publicly-funded and primarily given by community health care providers except for ones given by public health as part of the school-based immunization program.

Under ISPA, routine childhood immunizations administered by community providers are to be reported to public health by families. OPH sends notice letters to parents and caregivers of children missing one or more ISPA vaccines according to their immunization records, on an annual basis. These notices inform parents and caregivers which vaccines are missing on their child's record, remind them to get their child immunized, and to report the immunizations to OPH.

Childhood Immunization Coverage by Age and Disease 

Children aged 7, 12, 13, and 17 are assessed by Public Health Ontario (PHO) for up-to-date immunization coverage, which is estimated as the percent who have received the recommended number of doses of a vaccine or have evidence of immunity at a given point in time (Table 1, Table 2, Table 3) [1-5]. Many children who are not up-to-date have received some, but not all, recommended doses in a vaccine series. The National Immunization Strategy's immunization coverage goals, updated in 2017, set coverage targets based on international standards and best practices [8]. Note that coverage estimates are limited to vaccinations reported to public health.

  • In the 2022-23 school year, the immunization coverage rate among 7-year-old students in Ottawa was approaching the national goal of 95% coverage for rubella and Meningococcal C conjugate (MCC) and it was below the national goal for other diseases (Table 1). [5]
  • In the 2022-23 school year, the immunization coverage rate among 17-year-old students in Ottawa reached the national goal of 95% coverage for rubella, was approaching the goal for measles, mumps and polio, and was below the goal for diphtheria, tetanus and pertussis (Table 2). [5]
  • The COVID-19 pandemic resulted in declines in immunization coverage between 2019-20 and 2021-22 in Ottawa. From 2021-22 to 2022-23, increases in coverage were observed for all childhood vaccines, with the exception of rubella, Hib and MCC (Table 1, Table 2, Table 3). [1-5]

School-based Immunization Program

There are three vaccines which are part of Ontario’s publicly funded school-based immunization program, typically delivered by public health to grade 7 students (~12-year-olds): hepatitis B, human papilloma virus (HPV), and quadrivalent meningococcal conjugate C (MCV4). Only MCV4 is required under ISPA.

  • In the 2022-23 school year, the immunization coverage rate for school-based vaccines in Ottawa was approaching the 90% national goal for MCV4 and was below the goal for hepatitis B and HPV (Table 3). [5

Exemptions

Exemptions for one or more ISPA-designated diseases can be issued on medical or non-medical grounds. A medical exemption can be granted in the case where a child has documented immunity or has a medical contraindication (e.g., immunosuppression, Guillain-Barré syndrome). Non-medical exemptions can be issued on religious or philosophical grounds.  

  • In Ottawa in school year 2023-24, less than 2% of 7- and 17-year-old students had a medical or philosophical exemption according to their immunization record. [12] 
 COVID-19 Pandemic Impacts on Routine Childhood Immunization Coverage
  • In Ottawa, the COVID-19 pandemic substantially disrupted access to routine childhood and school-based immunizations. The closure of primary care offices and schools, the shift to virtual care, stay-at-home orders, early retirement of health care providers, and the diversion of public health resources to COVID-19 activities all impacted vaccination rates. [7]
  • The estimated total number of doses of routine immunizations missed between 2020 and 2022 among children and youth in Ottawa was over 40,000. Of these, approximately 15,000 were missed doses of vaccines which protect against measles. [7]
  • In addition, the COVID-19 pandemic also impacted reporting of immunizations to public health. Between March 2020 until school year 2022-23, OPH’s ISPA surveillance activities (e.g., notice letters) to remind families to report their child(ren)’s immunizations were paused. As a result, many children have incomplete immunization records which limits the accuracy of coverage estimates[7] 

Influenza Vaccinations

Influenza, commonly known as the "flu", is a respiratory infection caused by the influenza virus. Influenza can easily spread from person to person and influenza virus circulation follows a seasonal pattern with most infections reported between fall and spring. Annual influenza immunization is the most effective way to protect against influenza. Each fall, Ontario’s Universal Influenza Immunization Program (UIIP) offers vaccination against seasonal influenza to all individuals 6 months of age and older who live, work, or go to school in Ontario. [9]

Ottawa residents can receive a seasonal influenza immunization from their health care provider, a pharmacist, or at an Ottawa Public Health clinic. While the UIIP offers immunization to all Ontarians, there are groups for which influenza immunization is prioritized, who are at high risk of complications or who those who are capable to transmitting influenza to those at high risk for complications. These include, for example, children under five years of age, older adults over 65 years of age, those with chronic conditions and health care workers. [9]

 Influenza Immunization Data
  • In 2019, 37% of Ottawa children and youth had received an influenza immunization in the past 12 months. Young children under age 5 were more likely to have received an influenza vaccine (49%) compared to older children aged 5-11 years (36%) and youth aged 12-17 years (31%) [11]
  • About half (51%) of Ottawa residents aged 18 years and older reported receiving an influenza immunization during the 2023/24 influenza season, similar to 2022/23 (50%) and 2020/21 (50%). [11]
  • Immunization rates are higher among older adults. During the 2023/24 influenza season, 42% of residents aged 18 to 64 years reported receiving an influenza immunization while 86% of residents 65 years of age and older received an influenza immunization (Figure 1). [11]
  • In 2023/24, over half (61%) of residents said they got their influenza immunization at a pharmacy and 24% at a doctor’s office. The proportion of residents receiving their influenza immunization from a pharmacy has increased over recent year (2016/17: 44%; 2019/20: 30%; 2020/21: 49%, 2022/23: 56%). [11]

 Immunization Surveillance by School

Each year, the immunization records of Ottawa school students are assessed by Ottawa Public Health’s Immunization program for compliance with the Immunization of School Pupils Act (ISPA). Parents are responsible for reporting their child(ren)’s immunization records to Ottawa Public Health. Based on this reported information parents are notified if their child(ren) do not have the required vaccinations for their age according to ISPA or a valid exemption on record. Post-surveillance vaccination coverage and philosophical exemption rates by Ottawa school are used to help tailor support to school boards, schools, parents/guardians, and others to ensure their child is up-to-date for all relevant ISPA vaccines for their age.
