FYI if there is a CVS near you, you can get a booster there regardless of your age. I got mine 3 weeks ago. They have a screener online you fill out online and age is not a question.

All you need is your vax card showing it's been 6 months since your last shot.

To boot, I couldn't get an appointment so I just walked in and saw they weren't busy and asked for a booster.
