I am interested in learning about the different side effects Pfizer, Moderna, and Johnson & Johnson vaccines possibly have on RA patients. My doctor happens to be on the conservative side and she shared with me that vaccines can cause RA situation to be worse, not just a flare temporarily. She suggests I only take Johnson & Johnson since the technology is very trustworthy and it may have a less strong negative impact on RA patients. Pfizer and Moderna are simply too much for RA patients. She now got me concerned. Would love to hear what others think about this subject and the experiences of other RA patients who have already taken the vaccines. Thanks.
