I've had 2 shots of the Moderna vaccine (Apr, then June) and no side effects other than the typical sore arm for a day or so afterwards - all good!

I've been on Remicade for err, cripes, about 17 yrs so I'm lucky that my AS is under really great control to the point of practically no symptoms and only 2 iritis attacks in all that time (my iritis used to be chronic). Rheumatologists here recommend that we get vaccinated, especially if on an immune suppressing med. A covid infection is the far greater danger, in my wee opinion. These vaccines have lots of solid data on good efficacy and safety now.

Hope everyone stays safe!
