The third was at pharmacies only and free only if you didn’t have insurance.
For people in the USA: The covid vaccine is free for people with insurance.
Additionally, at least some doctor’s offices have it (mine does, but I don’t want to assume they all do), and there are vaccine clinics where they do flu/covid/etc that show up periodically if that’s more your style.
I’m not specifically calling out the user I quoted, just making a general statement because I’ve seen that exact sentiment (“the covid vaccine is no longer free”) like 4 or 5 times on lemmy in just the past day. It’s disinformation/misinformation and it leads to situations where misinformed people decide not to get vaccinated, in part, because they think it’s going to cost them money.
