Covid booster shots

Covid booster shots do not make sense from a hypothetical standpoint. Once your white blood cells adapt to the Covid-19 virus there is no expiration date to that adaptation. The vaccine should only stop working if the virus mutates. And if the virus mutates causing the vaccine effectiveness to be negated then you need a *different* vaccine - not the same one, again. What is wrong with the logic here?
