My doc says the COVID vaccine will only be 20-40% effective if you get it while on a biologic. I have no idea where he got that number, maybe its the effectiveness of any vaccine. So I am not worried about getting the vaccine, just that it won't protect me as well as if I got it when not on any meds . Gary, your Stelera schedule looks similar to mine- I just started in November, have had the initial infusion and now 2 injections, 40% improvement, possibly going to every 4 week dosing. I'm also in Ontario,( Thunder Bay), just curious as to where you are getting treated?
