I read the first couple tweets but then skipped down to about #14 because I didn’t really get all the scientific stuff. But what I got out of it is that if they can identify those that have gotten the virus and those that haven’t, they can form some sort of plan based on the assay they have. Again, I don’t understand the mumbojumbo going on in these tweets but maybe it sounds like they can use serum from those that already got the virus and recovered? I’m having trouble reading the tweets as a layman so maybe @PTCVOL or @Devolunteer could translate for us.
