Today, Governor of California Jerry Brown signed a new vaccination law into effect—one of the toughest in the nation. The Los Angeles Times reports that Brown cited "weakened public health defenses" against preventable diseases like measles as part of the reason why California is getting this new law. Last December, an outbreak of measles started in Disneyland and spread, infecting 150 people. 

Not everyone is on board with the new law—take Jim Carrey. He called Gov. Brown a "corporate fascist" and said the new law would lead to "poisoning more children."
