Oh, the new CDC recommendations have already been condemned by every scientist I follow. Largely because there's no way to tell who's really vaccinated and who's faking it.
I mean, they gave us those nifty cards...
There were a slew of issues that had arisen. On the one hand, the CDC
needed to revise its guidance. Based on what I've seen (both anecdotally and in whatever data sources exist), the complete lack of a change in much of the guidance over the last few months had led folks to start ignoring it because the "asks" in it were not closely connected with realistic expectations. Implicitly telling a fully-vaccinated family to walk on eggshells when getting together just wasn't going to cut it, and IIRC the guidance that
was issued was rather complicated (to put it mildly).
I think there's a case that the CDC veered too far to the other side, and the idea that, for example, one activity is safe
sans mask per their guidance in Florida or Texas but not in California or New York comes across as something of a disconnect (obviously, the phrasing was aimed at avoiding CDC guidance being in
direct opposition to existing rules rather than merely being vaguely disconnected from it). It really feels like the CDC's guidance is "Once you get your shots and it's been two weeks, you're not our problem".
But the bottom line is that in a case like this, it can be better to issue guidance that you think people will actually listen to than guidance that is "right" but that folks are going to simply ignore. The best analogy here is the fight over abstinence-only sex ed...yes, not having sex means you're not going to get pregnant or (for the most part) pick up an STD, but the reality is that if that's all you teach, a lot of folks are going to ignore the advice because something something biological imperatives. And of course, if you start giving too much advice that folks ignore, that reduces the chance that folks will listen to you later (here, the best analogy is probably the 55 MPH speed limit...if you tell folks to go 55
everywhere, sooner or later they start judging a safe speed for themselves).
So put plainly, the CDC was trying to set a 55 MPH speed limit and I think that they found a bunch of vaccinated folks were saying "Screw this" and doing 90, so they tried compromising on a 75 MPH speed limit for them. I don't think this was a fight they won, or that they were
going to win, but I think that's essentially what happened.
