COVID-19: Effectiveness and benefits of vaccination

Vaccination is one of the most effective ways to protect our families, communities and ourselves against COVID-19. Evidence indicates that vaccines are very effective at preventing severe illness, hospitalization and death from COVID-19, including against Alpha and Delta variants of concern. However, there’s a small percentage of the population who are vaccinated that will still be infected with COVID-19 if they’re exposed to the virus.
