I think Novavax is being purposely delayed so Pfizer and Moderna can grab the entire US market.
Another reason I’ll go with J&J. No boosters. I believe once you get one of the shots you’re “locked” in. Of course if everyone did J&J, then I’m sure they’d say you must get an mRNA shot too and it’s ok to do so even if you had the J&J shot.
BTW: only reason I’m going to get the J&J...looks like they are going to force me to take it.
