But to require this vaccine is probably not necessary.
I would prefer to save the required vaccines to those that cover diseases that may have the potential to spread quickly to epidemic proportions. For that virus to advance to cervical cancer would take years.
I am still trying to figure out how an immunization such as this would encourage promiscuity.

You just don't hear alot of teens voicing fear of human papiloma virus.
Now an AIDS vaccine......which could clearly "encourage" some to take on premarital sex earlier...I might be ok with that vaccine being manditory - the effects of AIDS are devastating to our citizens and our resources.
