CoVPN 3006 – Prevent COVID U

The COVID-19 Prevention Network (CoVPN) is conducting a study across the US to learn whether the Moderna EUA COVID-19 vaccine prevents infection with SARS-CoV-2 and whether it prevents transmission of the SARS-CoV-2 virus that causes COVID-19 disease. Over about 4-5 months, 12,000 people ages 18-29 will get injections of the Moderna EUA COVID-19 vaccine to help us learn if vaccinated people can still be infected with SARS-CoV-2, and if they are able to spread the virus to other people. Another 6,000 people who do not wish to be vaccinated will be enrolled as an observational group. Importantly, the people who enroll will be asked to refer their close contacts, such as family members, coworkers and friends, to take part as well. These close contacts will help us monitor for transmission to others.  While we already know that the Moderna EUA vaccine does a great job of preventing COVID-19 illness, hospitalization, and death, this study will help us understand the remaining questions about infection among people who are vaccinated, and how vaccination affects transmission to those around them. 

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.
