  • Do the vaccines prevent infection with coronavirus?
  • How long do the vaccine effects last? Will booster shots be needed?
  • Are the vaccines safe for children under 16 years, pregnant people, and people with weaker immune systems?

Masks Are Still Needed to Stop the Spread of Coronavirus

Until we know if mRNA vaccines protect against infection, masks are still needed to stop the spread of coronavirus. Masks are the best way to stop the spread of droplets from your mouth and nose to others.

Together we can help end uncertainty. Join us.

We need your help to keep learning and improving vaccines against COVID-19. We made history with safe and effective vaccines and we’ll keep working as long as there are people to protect, variants emerging, and research answers needed to end this pandemic. To participate:

  • Fill out the survey again so we have your most current information to match you with a study, even if you filled it out previously!
  • If you haven’t registered to volunteer before, sign up today. There’s still a lot we can do together for those we love.
