A Texas Senate panel has approved a bill to bar state health officials from requiring schoolgirls to be vaccinated against the human papilloma virus.
Governor Rick Perry in February issued an executive order requiring the HPV vaccine to help prevent some types of cervical cancer.
Perry's order outraged lawmakers from both parties and much of his social conservative base, who questioned the vaccine's safety, plus raised parental control issues.
The bill approved by the Texas House would prohibit the state from adding the HPV vaccine to the list of shots required for school attendance.
The Senate committee added a provision that would prompt lawmakers to review the ban in 2011.
