Not all students in schools are vaccinated

State law says all children must be vaccinated by the time they set foot in the classroom. But health officials say more and more parents are using an exemption to opt out of it.

Texas law allows for an exemption from immunizations for reasons of conscience, including a religious belief. To claim an exemption due to reasons of conscience, a student's parent or legal guardian must request, sign, and submit an official DSHS affidavit form to the child's school. The affidavit is valid for two years.

Below are the 2015-2016 conscientious exemptions by school district as reported to the Texas Department of State Health Services.
