I don't know how you could have been on FR for any length of time without being up to date on the Gardasil knock down, drag out debate. Nobody was EVER forced to be vaccinated. It was never advocated that anybody be "forced" to be vaccinated and no one was in fact vaccinated.
Long story short: Perry thought it would be a good idea for school girls to be vaccinated because he "hates Cancer". He issued an executive order requiring such but with an opt-out. (BTW, Texas school children cannot attend school w/o being up to date on their vaccinations).
There was a lot of public backlash and Perry let it drop. He's admitted his mistake and I think learned a valuable lesson about issuing executive orders.
I read this my Michelle Malkin. She has more detail and I agree with her assessments.
