CA lawmakers just approved one of the toughest mandatory vaccine laws

California's General Assembly just approved a controversial bill that will require schoolchildren to be vaccinated — unless they have a medical reason for opting out. The bill, SB277, would change the law so that people could no longer refuse to get vaccines for religious or philosophical reasons — measures parents sometimes try to take on behalf of their kids. The bill was a response to a large measles outbreak that originated at the Disneyland theme park in the state in December. Since then, more than 160 people across the US have been diagnosed with the disease (the majority of them in California).
