@lblauvel, I'm guessing no one will be able to provide a recommendation for folks with PMR and not on prednisone. I would put myself in that category since PMR really never just goes away but rather just goes into remission after treatment (just my non medical opinion). I get yearly flu shots and my only reaction has been a sore arm for a day at most. I am planning to get the COVID vaccine when it's my turn but I'm not sure when that will be.
