I think it's conceivable that some shows can start to open in the fall (I'd imagine the first back will be Hamilton, as has been reported elsewhere, and the new productions that could most give Broadway a shot of adrenaline - The Music Man, Plaza Suite and the return of American Utopia. (The dates for Plaza Suite will have to move again, surely - it's scheduled for this summer but won't happen that soon. American Utopia is scheduled to return Sept. 17th, which sounds more plausible, especially as they won't need much rehearsal, and The Music Man smartly has its first preview scheduled for Dec. 20th, which will be more than a year from when the first vaccines went out to the first people).
Regarding anti-vaccers and whether or not people will get the shots, hough, you can bet that the fine print we all never read on all those Telecharge and Ticketmaster terms of service will be updated to include something like "By purchasing seats for this performance, the ticketholder assumes all responsibility for any airborne illnesses that may be contracted on the premises." Nothing that wasn't already understood, mind you, for everything from the common cold to perfume allergies – but I'm certain it will be more explicitly laid out. So that when the New York Post inevitably runs a headline saying "They Caught Covid at Come From Away", or "Broadway Bodily Breakdown: Caroline, Or Covid?", no one involved with the productions, the theaters, or the ticketing agents can be in any way held liable for others' failure to inoculate themselves.
