Saying "It's equally stupid to claim that the vaccines do no good" is inappropriate for this thread, which was likely why you were downvoted.

Vaccines have proven useful for protecting people from dangerous/incurable diseases, but not all vaccines are the standard inactivated type that was proven safest...
