Since Jan. 1, 96% of all confirmed cases in Alberta were either unvaccinated or diagnosed within two weeks of receiving their first dose while their immunity was still building.
Vaccines provide a very high level of protection against severe outcomes. Since June 1, 91% of COVID-19 deaths in Alberta and 95% of hospital and ICU admissions were in those who did not have two doses of vaccine. Vaccines save lives.
