Cases and rates by vaccination status


Please note that Cases by Vaccination Status data will no longer be published as of June 30, 2022.

This data set relied on COVID-19 case counts based on molecular testing (e.g. PCR). As of December 2021, Ontario’s testing strategy began to limit access to molecular testing to people working and living in highest risk settings and people at highest risk of adverse outcomes of infection. As these groups have very high vaccination rates, this led to us disproportionately identifying cases in people who were fully vaccinated or fully vaccinated with a booster. As a result, these data no longer accurately depict the true risk of infection in Ontario. COVID-19 vaccines remain effective at preventing severe illness, hospitalization, and death.
