Boosted
Maybe I'll be back in six months for the booster's booster.

It's not the store I really want to endorse, but it is where I very easily got an appointment for my Moderna booster. Maybe I'll be back in six months for the booster's booster. My arm is quite sore and I wouldn't want it any other way. Am I worried about side-effects? Well let's put it this way: I'm running a half marathon tomorrow and that has no impact on scheduling this appointment last-minute.
