In greater NYC area you can just make an appointment and walk into any CVS or Walgreens and add a booster of your choice, every 2+ months (which is the frequency CDC mentions, though research graphs suggest moderate booster effect doesn't disappear for 6 - 9 months), and supposedly your insurance will cover it if you're in a window the federal government isn't covering it, but so far they still seem to be covering it. Visitors from outside the US are still being able to walk in and get it as well. YMMV etc. etc., but this is accurate in greater NYC area as of January/February 2024.
