AUSTIN, Texas -- A new survey shows Republican voters overwhelmingly support school immunization requirements even as the anti-vaccination movement grows.

According to a report from the Texas Public Health Coalition, 86 percent of Republican primary voters said they support current laws that require school age children to be immunized. Of those, 71 percent said they strongly support the laws.

Texas does allow immunization exemptions in two cases: Doctors order it or parents choose to opt out of vaccinating their children for reasons of conscience or religious belief. Recent state data shows more parents are opting out of vaccinating their kids.

According to Texas' Health and Human Services Department, nearly 57,000 students claimed at least one non-medical exemption last school year. That’s about 4000 more than the year before.

"I think we have real public health concerns and concerns about our kids safety with growing exemptions to immunization that are not based on a real medical cause," said Dr. Donald Murphy, an Austin pediatrician.
