It’s not a vaccine if you have to keep getting boosters. No booster for mumps, measles, chicken pox etc. Even a tetanus shot lasts 10 years. Not only is this abomination no where near as effective as was originally touted, but it only lasts couple of months and is useless against the variants.
Other than that it’s good. Please.
Some vaccines are three course shots. Some wear off over time. Tetanus and pertussis come to mind. But I've never heard of one that wears off so quickly. Probably because cold viruses mutate so quickly.
