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.
It's also a matter of what you are trying to achieve with the boosters. For a lot of people boosters are really only needed to prevent infection, since even un-boosted the vaccines still appear to protect against serious illness.
