bad news: only 24% of san francisco residents are up-to-date on their covid vaccines :(
good news: this is a fantastic time to get your covid & flu vaccines! the winter waves have barely started so you'll have peak protection when you need it most.

i got my vaccines at this site, and i recommend it whether or not you have insurance. they bill insured people (no cost to you) in order to provide free vaccines for uninsured people.
