Speaking of back to masks... I got the following short article from my niece, who's a virologist in the same department as the authors (whom she speaks very highly of), at the Univ of Colorado. The authors do the best job of anyone I've read at making this info simple to follow for the non-academic. And this is first hand knowledge from the experts themselves, not from a journalist who just interviewed someone. 
Bottom line is that, because of the Delta variant, in some situations (i.e. indoors, in public places), they're going back to mask wearing, even though fully vaccinated.
