So far two days into having the first of Pfizer COVID-19 vaccine I haven’t had any real side effects. Maybe yesterday I was a bit out of it, but I kind of had a light breakfast and I didn’t sleep that well the night before. I could feel a little bit in the arm this morning but it was barely noticeable. A little bit achy, but not really, and it could be the weather as anything with some residual lyme disease — but I’ve certainly felt a lot worse on other wet days.
