Yes. No vaccine is 100 percent effective, and the CDC recommends that everyone continues using all the tools available to us to help stop this pandemic, such as covering your mouth and nose with a mask, washing hands often, staying at least six feet away from others, following CDC travel guidance, following quarantine guidance after an exposure to someone with COVID-19, and following any applicable workplace or school guidance. Together, COVID-19 vaccination and following CDC’s recommendations on how to protect yourself and others, offers the best protection from getting and spreading COVID-19.
Experts need to understand more about the protection from being contagious that COVID-19 vaccines provide before deciding to change recommendations on steps everyone should take to slow the spread of the virus that causes COVID-19. We know it significantly reduces symptomatic and severe disease, but not whether it completely protects from infecting others. Other factors, including how many people get vaccinated and how the virus is spreading in communities, will also affect this decision.
