Or if you are lucky nothing. AZ kicked my ass to the curb with the first. I had Pfizer as my 2nd and no issues at all. Fingers crossed
I did okay with AZ. Felt like I had an achy full body hangover most of the next day, but it wasn't terrible. Got Moderna today... we'll see. Fortunately I don't have anything major that needs doing tomorrow if things do go sideways!
