What the title says, I was talking to someone last month and they'd mentioned how they get boosters on their own schedule and that because of the dysfunctional nature of US healthcare no one keeps track or cares. I switched insurance this January to a new insurance company and it seemed like a good time to test it out. I just said that I'd lost my card and my last shot was earlier than when the bivalent boosters were released and went to a different pharmacy than I had previously had gone to. I know a few people who have had breakthrough cases since getting their bivalent boosters in September and wanted to avoid this. I figured I would share this info since we're more or less on our own for preventing infection.
