Jim Carrey is not happy with California Gov. Jerry Brown.
The actor, 53, believes there is a link between vaccines and autism and called Brown a "corporate fascist" after he signed into law one of the strictest immunization programs in the country Tuesday.
The bill would require kids at daycares and schools to be vaccinated unless there's a serious medical reason why they shouldn't be. Personal or religious exemptions would not be permitted, and if parents disagree, they can home-school their kids. Only two states, Mississippi and West Virginia, are as strict.
Carrey has been an activist on the hotly debated issue since his relationship with Jenny McCarthy, who believes her son's autism was caused by vaccines.
The Dumb and Dumber To actor took to Twitter Tuesday to vent his frustrations over the bill and rally support from his 14.7 million followers:
According the Centers for Disease Control and Prevention, however, there is "no link between thimerosal-containing vaccines and [autism], as well as no link between the measles, mumps, and rubella (MMR) vaccine and [autism] in children."
Other celebrities who are anti- vaccination include Mayim Bialik, Kristin Cavallari, Rob Schneider and Alicia Silverstone. Many other stars are pro-vaccination, including Kristen Bell, Jennifer Garner, Sarah Michelle Gellar, Jennifer Lopez and Keri Russell. "When Lincoln was born [in 2013], the whooping cough epidemic was growing, and before she was 2 months old, we simply said [to friends], 'You have to get a whooping cough vaccination if you are going to hold our baby,'" Bell has said. "It's a very simple logic: I believe in trusting doctors, not know-it-alls."
Gov. Brown has until next weekend to decide what to do.
