If you have had the initial two doses and a (bivalent) booster since September, you’re up to date.

Unfortunately, so few people have gotten the bivalent booster that there’s no herd effect. Everyone is getting exposed to someone with COVID. People still getting COVID because they are the small percent the vaccine doesn’t protect make it impossible to know when protection is wearing off for everyone else.
