PuoskariIf the vaccine's function mainly is to protect from the severe effects, and it doesn't necessarily stop spreading the virus
this feels like a simple thing to understand but it seems to be a point that goes over the head of many online skeptics (bear with me, i do not know how to write this without sounding condescending).
if you get the vaccine, you are much less likely to catch the virus, and because you are much less likely to catch the virus, you are also less likely to spread the virus.
the point of the vaccine is to not only protect yourself but to protect others.
