How do the vaccines “help people around them”? I’m vaccinated against polio and typhoid and a slew of other things. I don’t need you to be vaccinated against those diseases for my vaccinations to work. This junk-science phenomenon is new with Covid.
So many these days don't give a flying **** about anything that doesn't affect them personally. Vaccinations are necessary not only to protect the person getting the shot but also
everyone they come into contact with - if you get sick, you are capable of getting others sick. No vaccination is 100% effective. You still have a small chance of getting sick if exposed to someone who is sick. Having others vaccinated against covid, or polio, means there will be less of that virus going around - less opportunity to get infected.
If you are vaccinated and come into contact with the virus, you
probably won't get sick (that's the vaccine working). If, however, you are vaccinated and
don't come into contact with the virus,
because everyone you run into is also vaccinated, then you have
zero chance of getting sick, instead of a
very small chance. This is how herd immunity works.
People who say, "well, I'm healthy, I don't need the covid vaccine, my immune system will protect me", are basically saying, "**** everyone else, I think I'll be fine". That's a ****** way to interact with society. Oh, and there are a lot of people on ventilators, clogging up ICUs around the country
right now, dying of covid, who said precisely that, "I'm healthy, I don't need the vaccine." And a lot of them likely infected other people along the way, simply because they don't care about anyone else, only about themselves.
(And to "my immune system will protect me": the vaccine is basically giving your immune system a dossier, saying, "hey, watch out for this bad guy, start building up your defenses now". Putting your faith in your immune system and then going out of your way to
not help your immune system prepare, makes no sense.)
