The benefits and good done by vaccinations, far outweigh the occasional side effect problem.
If there is any doubt in you mind, you can study public health science, statistics, probability.
@truth_seeker VERY true,but we must be careful to balance public health with public rights. Without the balance we have tyranny,and very few people actually want that.
BTW,I am old enough to remember when the polio vaccination first came out. Vaccinations were so new back then they were voluntary,and parents had to sign statements giving the schools permission to vaccinate their children. There were even "public service announcements" on tv,which I believe were the first ever,promoting the vaccinations and showing examples of what COULD happen to your children if they weren't vaccinated. I am slightly claustrophobic,and still get the shivers to this very day when I think about being locked away in an iron lung for life.
Neither of my parents had more than a 5th grade education,and really had no idea if they should sign to give me the shots,or listen to the bible thumpers who were screaming about it being a "sign of Satan because it is GAWDS will the government is challenging!"
I insisted they sign to give me the damn shots,so they signed.
Lucky for me they did,too. I had a reaction to the vaccination,and was bedridden for months,and even had to learn to walk all over again. Which means the disease was already in my system when I got the shot. I met someone in the 70's who had the same reactions to it that I did,and we agreed in every respect about how lucky we were to have gotten the shots.
The vast majority of the children that got them had no reaction at all,but the one thing we know for sure is there have been no polio outbreaks since Jonas Salk invented the vaccination.
