My MIL has rheumatoid arthritis which came on suddenly last year out of nowhere. It’s always in the back of your head that perhaps it has some link to the vaccination but I’m withholding judgment until proper statistics are available. She was a ( daily ) smoker but has given up since the diagnosis. Note that everyone in both families are vaccinated, boosted etc and it has not changed her opinion on vaccination.
