Two California state lawmakers are seeking to strengthen California's vaccine laws by eliminating an exemption based on personal beliefs.
The bill proposed Wednesday comes as dozens of people have fallen ill from a measles outbreak that started at Disneyland.
Democratic Sens. Richard Pan, a Sacramento doctor, and Ben Allen, a former Santa Monica school board member, proposed legislation Wednesday to change a state law that allows parents to opt out of vaccines based on personal belief if they see a medical professional first.
The legislation would allow exemptions only for medical reasons. But Pan says he would consider adding an exemption for religious beliefs, as the current law allows.
Most states allow exemptions for personal or religious beliefs. Only Mississippi and West Virginia restrict exemptions to medical issues.
