This is well-intentioned but false. The vaccines can send you to the hospital (side-effects). It's rare but happens. Similarly, you can be vaccinated, get infected with SARS-2, and end up in the hospital, so it's not even true that they avoid hospitalization from SARS-2 itself completely. (They help a lot with hosp/death from the virus, to be clear)
The vaccine can almost certainly send a few people to the hospital in the same manner that an airbag could almost certainly cause injuries during an accident.
It's very different from a natural infectionimo.
I know that it's a very unpopular opinion, but i'd say your statement is unfortunately still not 100% proven for every individual. A healthy 20 yo has "almost" 0 chance of having bad outcome from the covid. He also has "almost" zero chance of doing a hearth infection from RNA vaccines, and we have no idea about the long term consequences of both virus and vaccines, since both are only a few years old.
Making definitive statements in this context is hard.
But explaining to that same 20 year old that he might unintentionally bring COVID home from college and proceed to unintentionally infect high-risk parents or grandparents? That's where the real damage would comes from.
The peace of mind knowing I'm not going to unintentionally kill off members of my family is priceless.
Unfortunately, the recent news on that front don't bring much hope. Vaccinated people can be infected, and transmit the virus to elderly people (the rate at which they do being currently debated among specialist, some claiming it is much less, other claiming it is just as much as non-vaccinated asymptomatic people).
I do know I need to be able to live with myself, and if I accidentally hurt someone I loved due to being careless in the face of a real threat - it would tear me up. I'm sure others feel the same, and I hope people can keep it up through the fatigue. :)
