Xeljanz here, My doc at U of Chicago said to definitely get the booster. Actually just did it yesterday. As an aside, also must have the 2 Shingrix vaccines,,,,one down,,,,one to go. Not to scare anyone but just be prepared, the covid vaccine didn't bother me (sore arm, some chills) the Shingrix vaccine knocked me out for 3 days. Good thing I didn't have anything important coming up.
The Shingrix shot gave me zero side effects other than a sore arm. I'm also on Xeljanz. I get my second Shingrix shot next month. My University of Chicago GI hasn't said anything to me about
