I also believe that the second COVID Pfizer vaccine sparked my PMR. The Pfizer and Moderna vaccines were of the mRNA type, which is uncommon for vaccines. I've never had a flu vaccine because they are only 18% effective and feed big pharma. I've had a shingles vaccine before Shingrix one came out--I'm still on the fence about getting this "newer and improved one." It is questionable that I ever had PMR since my new rheumatologist believes that the fact I only had symptons while laying down is not indicative of PMR. I was a extremely healthy prior to the onset of my night pains-- I rarely ever got sick. If I ever get another vaccination, I will avoid the mRNA type.
