Exactly why I held out for the J&J vaccine. I don’t know if it’s considered a “co-morbidity”, but I have epilepsy and am already on two medications for that (after years of trial and error) - so didn’t want to be more experimental than I had to be with a vaccine.
I’ve also been holding out for the J&J vaccine for a couple reasons. It’s only one shot and also it’s not using mRNA. Our local Walmarts are getting them in this week so I signed up online and will get it Thursday. It specifically said it was the J&J shot.
