Normal vaccines are used to immunize people against a disease.
Immunize means make (a person or animal) resistant to a particular infectious disease or pathogen, typically by vaccination.
The only “vaccine” that”limits the damage” is the covid vax. I got it twice and still ended up with covid. My brother had it to and his was just as mild and he wasnt vaxxed.
The idea that it limits the damage is questionable at best.
I’m all ears though, show me data and i’d consider your viewpoint but I just dont think it exists…
