The bill, which eliminates the so-called personal beliefs exemption allowing parents to forego vaccinations if opposed to them for any reason, was introduced after a measles outbreak at Disneyland last year that sickened more than 100 people.
"The personal beliefs exemption is endangering the public," said Democratic state Senator Richard Pan, a pediatrician and co-author of the bill. The measure still allows children to attend school without vaccinations for medical reasons.
In recent years, vaccination rates at many California schools have plummeted as parents, some of whom fear a link between vaccines and autism, have declined to inoculate their children against such diseases as polio and measles.
