AUSTIN – As lawmakers prepare to debate an override of the governor's order that schoolgirls be inoculated against the virus that causes cervical cancer, a group of legislators wants the state to produce a brochure about the vaccine.

"We want families to know the facts," said state Rep. Dennis Bonnen, a Republican. "No one here is against a family studying the facts for themselves and deciding this is the right thing to do. ... What we don't want to do is tell them that we know better than them."

Bonnen is co-sponsoring a bill that would direct the state to produce and distribute informational materials about vaccines against the human papillomavirus, or HPV. The brochure would be distributed at doctor's offices, health clinics and hospitals.

The bill will be discussed Monday at a hearing also to feature debate about a measure aimed at overriding Perry's Feb. 2 order, which requires girls entering the sixth grade as of September 2008 to be vaccinated. Opponents say the order intrudes into families' lives and contradicts Texas' abstinence-only sex education policies.

Perry said Thursday that he is open to changes to his order but would not say whether he would veto a measure eliminating the vaccine requirement.

"I'm not rigid," he said. "If the Legislature has some restrictions that they want to put on this, I'm highly respectful of this process."

New Jersey-based Merck & Co.'s Gardasil vaccine is the only HPV vaccine on the market. It protects girls and women against the strains of HPV that cause most cases of cervical cancer and genital warts.
