We have immune systems for a reason. Let them do their jobs. I don't know why people seem to think they are doing something beneficial for themselves by pumping themselves full of vaccines.
Vaccines have the virus in them to begin with, which is why some people have very bad reactions because you're effectively infecting yourself to build anti-bodies. However they like to put other things in vaccines that are not beneficial in anyway.
Regardless of what's in the vaccines, it's always nice to see advancements, however I am skeptical of it's claims. Also, as always _02 makes great points
But honestly, I don't care if people want to vaccinate themselves, as long as they don't think it's ok to forcefully make me take it or any other vaccine for that matter, because I won't. And I'll stick to that as I rarely get sick, I honestly don't even remember the last time I was sick, had to been a few years ago now.
