Why is this a big deal? I also got my first shot in January in Florida and I am under 60. Florida had TONS of vaccine available early on. In fact, due to the defrosting process, the vaccine sites had to discard quite a few doses at the end of each shift (once they were defrosted they had to be used within 30 minutes or so, and they came in batches of 40 or 80). And THAT is how I got mine early. At the end of each shift, they had 5, 10, 20 doses defrosted, so they literally would grab people off the walking paths or from the parking lots (vaccination sites were parks, and parking lots at malls or other large places) and try to convince them to take the shot. So at the end of a shift in late-Jan, I drove over to the nearest site, hung out for 20 minutes nearby, and at the end when they were looking for people to use the defrosted vaccine, I made myself available.
Meanwhile my friends and relatives in NY were desperately trying to get vaccinated, but NY was still wrangling about which sites to use (and if regular union rules would need to apply, and if the usual graft needed to be spread, etc). My mom lost 3 cousins to covid in NY in April-June, they would have loved some vaccine in Jan/Feb.
