Not talking in circles I think - I'm happy with where we landed. Sorry I started off harsh. You sounded too close to an antivaxxer trying to pass your opinions off as authoritative, and semantics really do matter there. I'm glad to see your ideas are much more nuanced and I think we largely agree at this point. To get any clearer we probably need input from proper vaccinologists. And hopefully they are informing policy, although that's no guarantee in this bungled response we've had.
