That's not necessarily true, though. We don't know that the effectiveness of the boosters will wane as the initial doses have. There are other cases where vaccines have needed a single booster and after that confer long-term protection. That may be the case here. No one has yet determined that repeated boosters will be necessary. Hopefully, they won't.That’s how I feel also, I’ve done what I can do. I “bought” myself another six months of relatively stress free freedom, hopefully in 6 months Covid will be under control, if not I’ll have to make another booster decision… but for now I’ve done what I can, that’s that.
