Edit:
I should probably also mention that there was a separate sub-study that more frequently monitored for SARS-CoV-2 infection. That study is now full (I think it was 3,000 total participants). In the sub-study, there are more in-person visits (at days 1, 15, 29, 43, 57, 90, 180, 360, 720). A COVID naval swab will be performed at each in-person visit as well as blood samples for "seasonal CoV" (not sure what that is). I presume the purpose of the sub-study is to measure the vaccines effectiveness at preventing infection in addition to preventing disease.
Every vaccine trial should have been doing that, this is critical. I mean what's the point otherwise, a job half done...
Moderna's chief medical officer says that vaccine trial results only show that they prevent people from getting severely sick — not necessarily that recipients won't still be able to transmit the virus
