Parents should not have to go to the trouble of opting out on something they should never have been forced to do in the first place.
If a family wants Gardasil for their daughter and the daughter agrees, then it should be available. What is wrong with that?
Although I think this is sound public health policy, I am sympathetic to the mandate requirement. But we already mandate vaccinations. Should Hep-B, MMR, Polio, etc no longer be mandatory?
