Well I got a COVID-19 booster (or placebo) Monday

I was in the Pfizer vaccine study and they asked me if I wanted to participate in the study for the booster shot. I’m about 99% sure I didn’t get the placebo, in fact this reaction has been worse than the other two. I started getting achy, tired and generally not feeling well Monday around 5pm and still feel achy and tired. And my arm hurts and is red at the injection site.

Hopefully it keeps me from getting a bad case of Covid.
