Data shows a decrease of antibodies in the blood after a few months. Yes, the older the more rapid. But younger people do not last very much longer so they need a booster too. This is already a known effect that happens also with other vaccines. So, when you have no medical condition that would indicate a problem with the booster get your shot.
Booster vaccines do not appear to be effective at all.
it is dumb if that's your only reason for not getting it. covid really doesn't give a shit if you're young. enough young people have died from covid OR have gotten long term complications from covid to where i wouldn't risk it. if you have access to a booster and you have no special medical considerations (e.g., immunocompromised) then i'd generally recommend you get one because the stats for boosted people are very very promising. leave a little less to chance.
