Why do I have to wear a mask if I’m vaccinated?

Because the Delta variant of COVID-19 is more contagious, wearing masks provides important additional protection to both unvaccinated and vaccinated people. While vaccinated people are at lower risk of getting COVID-19 than unvaccinated people (and have a lower risk of severe outcomes), well-fitting masks further reduce the chances that you are exposed to the virus and unintentionally spread the virus to unvaccinated people, including children. Masking is a tool that is part of a collective strategy to reduce risks, particularly at times when high levels of virus are spreading in the community.
