Find a Study Site - Com-COV3

  In response to the JCVI recommendation that children aged 12 to 15 should be invited for a second dose of COVID-19 vaccine at 3 months after their first dose, we will be deferring new recruitment to COMCOV3 while we analyse data from the 148 participants already recruited to this study. Participants already recruited to this study who are yet to have their second dose will still be able to receive this according to a revised protocol, available here.
COMCOV3 participants can contact their study site for more information.
If members of the public wish to register their interest in being involved on the ongoing study they can sign up at one of our study sites, below.  Study Site Teams are working through responses and will contact you directly with further information.
