People should make decisions on whether or not to accept vaccines based on whether they are safe and effective or not, not based on what some stupid religious leaders tell them. If parents think vaccines (certain ones or in general) are unnecessary, dangerous, and worthless, they should have the freedom to reject the shot(s) they feel are worthless and/or dangerous while accepting any shots they feel are safe and reasonably effective. And, if they feel that certain vitamins, along with or instead of the shots, are as good, they should be free to take those vitamins.
And do so based on independent research or actual case history, not based on what some idiot that knows nothing about these things tells them. It is easy for someone to issue a blanket ban on vaccines when there are some that actually work (along with others that don't). Later, that ban is taken down--what happens to those that got sick because they didn't take a shot that actually was good? And, once the ban is gone, people are supposed to get their shots whether or not they are bad?
