I am eligible for the Moderna booster (had second shot back in February) but I'm holding off till after my concert on the 18th. I don't want to risk losing a day of practicing to feeling lousy with after-effects.

I'm about 18 hours post-Moderna #3. Modest pain at the injection site. A little bit achy overall. No fever or nausea, or any of the other potential side effects. Certainly more noticeable than after a flu shot, but no big deal either.

I'm getting mine Monday! Hopefully my side effects will be mild as well. My reactions to the first two were pretty basic: sore arm, bleah feeling that a nap and some Tylenol took care of.
