The measure, if signed by Governor Jerry Brown following Senate approval of several minor amendments, would be among the strictest mandatory vaccination laws in the U.S., the Los Angeles _Times_ reported. The only way for children starting school to avoid a vaccination against whooping cough and measles would be for a doctor to sign off on an exemption due to a medical condition, like an immune system deficiency or an allergy. The move comes in the months after a measles outbreak that sickened some 130 people, including visitors to Disneyland in Anaheim, Calif.
