Overview
The purpose of this analysis is to:
- estimate vaccination coverage for COVID-19 additional dosesFootnote 1 among adults 18 years and older in Canada using data from the Canadian Community Health Survey (CCHS)
- compare vaccination coverage for COVID-19 additional dosesFootnote 1 by different sociodemographic characteristics, such as:
- age
- gender
- province of residence
- level of education
- dwelling ownership status
- racial or Indigenous identity
- number of young children in the household
- immigration status
- first language spoken
- supplement information already collected by the Canadian COVID-19 Vaccination Coverage Surveillance System
- inform decisions regarding COVID-19 booster dose campaigns
Highlights
Between February to June 2022:
- A majority of people 18 years and older living in the provinces had received at least 1 dose of a COVID-19 vaccine (95%)
- More than half of the adult population (62%) had received at least 1 additional dose of a COVID-19 vaccine beyond their primary series
- Additional dose coverage was lower among:
- residents in Alberta
- males
- younger age groups
- those with lower education
- renters
- those with young children in the household
- immigrants
- those whose first language were neither English nor French
- Black and Arab individuals
Survey collection methodology
The CCHS is an ongoing annual cross-sectional survey conducted by Statistics Canada that collects health-related information for the Canadian population at the sub-provincial level of geography. The primary use of the CCHS data is for health surveillance and population health research. Questions on COVID-19 vaccination were added to the CCHS in 2020. Starting in 2022, Electronic Questionnaires were used for data collection and computer assisted telephone interviewing (CATI) were used for follow-up of non-responses. Please refer to Statistics Canada for more information on the CCHS and the methodology of the survey, including the questionnaire.
The CCHS February to June 2022 component included people 12 years of age and over living in the 10 provinces except:
- full-time members of the Canadian Forces
- people living in institutions
- children aged 12 to 17 that are living in foster care
- people living on-reserve and other Indigenous settlements in the provinces
- persons living in the Quebec regions of Région du Nunavik and Région des Terres-Cries-de-la-Baie-James
Data selected for this analysis
The present analysis used data from the first 2 collection periods of the 2022 CCHS and focused on individuals aged 18 and older. The first collection period (February to early May 2022) gathered data from 16,066 adults, and the second collection period (April to June 2022) had 16,432 respondents. The response rate was higher in the second collection period (49%). Overall, a total of 32,498 participants were included in the analysis. (Table 1)

Additional dose coverage estimates comparison
Although the CCHS provides insights into COVID-19 additional dose coverage in Canada by sociodemographic factors, the Canadian COVID-19 Vaccination Coverage Surveillance System (CCVCSS) provides the most reliable vaccination coverage estimates because they are based on the entire population rather than a sample.
Comparing COVID-19 vaccination coverage from the CCVCSS to those estimated over the two CCHS 2022 collection periods (Table 3):
- Overall, the CCHS overestimates COVID-19 additional dose coverage by approximately 5%, which may be explained by differences between the CCHS respondents and the general population.
- According to the data from the CCVCSS, as of March 27, 2022 (at the midpoint of the first collection period), 56% of the population 18 years and older had received at least 1 additional dose of a COVID-19 vaccine; 57% as of May 22, 2022 at the midpoint of the second collection period; and 57% as of April 24, 2022 at the midpoint of the 2 collection periods combined.
| CCHS collection period | Data from the CCHS | CCVCSS data as of | Data from the CCVCSS |
|---|---|---|---|
| 1 (February 9, 2022, to May 7, 2022) |
63% | March 27, 2022 | 56% |
| 2 (April 2, 2022, to June 30, 2022) |
61% | May 22, 2022 | 57% |
| Combined (February 9, 2022, to June 30, 2022) |
62% | April 24, 2022 | 57% |

Additional dose is defined as any dose(s) received after the completion of a 1-dose or 2-dose vaccine primary series. (https://www.canada.ca/en/public-health/services/publications/healthy-living/canadian-immunization-guide-part-4-active-vaccines/page-26-covid-19-vaccine.html#t1) They are mostly booster doses but may include additional doses given for other reasons.
