An ex of mine worked for an alternative health clinic and swore that she wouldn't vaccinate her kids due to perceived risks from the vaccinations themselves. This fake "non-vaccination" religion thing was a common topic where she worked.
Now she's pregnant (by her new husband, not me of course), and I can't help but wonder if she's going to stick to her guns in doing this. Of course, she also claimed that she would do natural childbirth at home with a midwife and no drugs, so it will be interesting to see if that happens as well.
As for vaccinations, I do personally believe that we vaccinate babies too young, and that the risks of doing this are hidden by the big drug companies. However, kids need some kind of vaccinations at some point, particularly in an increasingly global society where there is more international travel and kids can be exposed to more diseases from other countries.
