There have been a number of incidences lately where people, especially children, have managed to catch a preventable disease in a crowded area like a cinema. These are diseases which could have been eradicated by now, but they haven't been because people are all up in arms over the safety of vaccines.
The thing is, even if vaccines do occasionally cause problems, they always stop diseases that can kill or maim your children. Not only that, but if your kid doesn't get the vaccine they can end up spreading the disease which can kill or maim other people's children.
It's not fair on everyone for you to not vaccinate your kids just because you are trying to prove a point (which has been proved over and over not to be true anyway.)
