Till now no evidence has been found that getting the shot can lead to any side-effect for people with rheumatoid conditions. There is certainly doubt among people whether the COVID shot will work on rheumatoid patients or not as they are already on autoimmune suppressant.

In general, after getting vaccinated people experience muscle pains, fever, and joint aches, but these outcomes just indicate that the vaccine is working. The redness and pain go away after a few days. It is a matter of concern only if the redness or tenderness where you got the shot increases after 24 hours or your side effects do not seem to be going away after a few days.
