Hi Bill @charlie333, Welcome to Mayo Clinic Connect. I think all of us that have had PMR can understand wanting to get off of prednisone as soon as possible even before COVID-19 reared it's ugly head. My PMR has been in remission a little over 2 years now but it took me a year and a half to taper off of prednisone. The first time my PMR showed up was about 10 years earlier and took me 3-1/2 years to taper off of prednisone. I'm 77 now and a high risk if I were to contract COVID-19.
I have no medical training or background but I don't think being on prednisone has anything to do with contracting COVID-19 but think it would make getting infected with COVID-19 worse for us. Have you talked to your rheumatologist about your concerns?
