The Public Health Agency of Canada (PHAC) continually releases data on COVID-19 and recently released stats on how COVID-19 affects the unvaccinated and vaccinated populations in Canada.
As of August 28, 2021, the bottom line is that over 80% of COVID-19 cases, hospitalizations and deaths occurred in unvaccinated people. By comparison, 2.5% or less of COVID-19 cases, hospitalizations and deaths occurred in fully vaccinated people. This stark difference, based on the data, shows that COVID-19 vaccines work to help prevent people from getting the virus and from experiencing serious health effects.
