It amazes me when people say things like “Science is a belief system, too, so if others believe vaccinations are a bad thing, it should be equally valid”, as if science was a religion. Without getting into problems with science (being something human beings do, it has its problems with orthodoxy, with refusing to entertain new ideas, the science establishment at times has shown itself to be as rigid as the Medieval Church or the Calvinists and the like), science is based on facts, on provable hypotheses, not on belief. More than a few of the anti vaxxers I have run across were religious fundamentalists , others were people just as equally looking for simple answers to complex problems (like the parents of autistic children looking for someone/something to blame), and their cherry picking ‘facts’, their claim of ‘studies’ that turn out to be basically self serving surveys or raw statistics that seem to imply causality, when all they seem to show is a correlation, which is not proof of anything.
The difference between vaccinations and other things people can choose to do (donate organs, or moral choice issues I won’t mention) is that those don’t directly affect the general public. With donating organs, you could argue that if people are required to donate organs if they die, there would be a lot more available for transplant, but given that transplant patients are not the entire population, and that potentially a large percent of organs gotten this way likely may not help (not in good shape to be transplanted, diseased, or not a genetic match), it isn’t a public health issue.
When someone doesn’t vaccinate others have pointed out the problems, the person in question, if they even don’t get sick, can be a carrier, and if there are enough unimmunized people it can allow the target disease not only a foothold, but also to mutate and change and potentially sicken people who were immunized against the original strain. Not to mention that those with compromised immune systems can pay the price for their stupidity.
I agree that those who go this route don’t care about others, whatever the root cause. It amazes me religious people can go a route like this that can seriously harm others, if you love others as you are supposed to in any belief system I know of, how can you knowingly not vaccinate and put others at risk? (and that is just my puzzlement,it makes no sense to me).
