While it is now apparent that vaccines lower hospitalization rates and the severity of the disease It is also true that hospitalizations are mostly limited to the elderly and those suffering from other health problems and not the general population, especially the younger cohorts. Meanwhile it seems that vaccination by itself is not reducing the number of covid cases in total. What exactly is the point of vaccinating the vast majority of people? Shouldn't the vaccines be administrated to people in those high-risk groups? To me it makes no sense to vaccinate those that have basically no risk of either hospitalization or death and in fact are mostly asymptomatic or have light symptoms. Wouldn't this just promote the spread of vaccine resistant variants? Why are we pretending natural immunity doesn't exist? That being said I'm not an expert in anything.

I'm genuinely confused as to what the vaccines and the mass vaccination drives are supposed to do at this point so explain it like I'm stupid. Full disclosure; I'm not vaccinated and am hesitant getting vaccinated, I'm 29, generally healthy and fit (in the sense that I'm not overweight or have any debilitating conditions). I do not know if I had covid but was tested negative three times over the course of a year or so.

tl;dr should I get vaccinated despite being in a low risk group and statistically unlikely to suffer any serious illness and why?
