I keep seeing everyone use the word "mandatory" regarding this vaccine. However, Gov. Perry's order provides for a very simple opt-out procedure for parents who don't want their girls to get the vaccine. To me, that means the government is not infering unduly - the government is sending parents a strong message "we believe this vaccine is likely to benefit your daughter's health, so unless you believe otherwise, she should get this vaccine." For parents who aren't informed or don't care, the opt out procedure uses the government's judgment. For parents who object to the vaccine, the parent's judgment is followed. This makes sense to me and seems to be the proper role for government.
