I can't say yet it needs further studies for those who are in charge of health organizations if they need to continue making boosters for Covid-19. Well, it is your own risk if you think you don't need a Covid-19 booster. If you think that you are healthy enough to fight that virus forever that will be good. On the other hand, if you think that you feel you are protected from the future Covid-19 viruses by having a booster shot that will be good too. Anyway, it is free in most countries. As long as you feel you are safe and protected in the choice that you like then do it.
