Jim Carrey is speaking out against new legislation requiring all public school children in California to be vaccinated starting in 2016.

Carrey, who has been an outspoken critic of vaccinations, said Gov. Jerry Brown needed to be stopped.

“California Gov says yes to poisoning more children with mercury and aluminum in manditory vaccines. This corporate fascist must be stopped,” Carrey tweeted of Brown, who signed the legislation Tuesday.

The new legislation removes personal belief exemptions to vaccinations for religious reasons. Carrey was once in a relationship with Jenny McCarthy, the public face of the anti-vaccination movement. She has said her son developed autism after receiving a vaccination.

Greed trumps reason again as Gov Brown moves closer to signing vaccine law in Cali. Sorry kids. It's just business. ;^[

They say mercury in fish is dangerous but forcing all of our children to be injected with mercury in thimerosol is no risk. Make sense?

I am not anti-vaccine. I am anti-thimerosal, anti-mercury. They have taken some of the mercury laden thimerosal out of vaccines. NOT ALL!

The CDC can't solve a problem they helped start. It's too risky to admit they have been wrong about mercury/thimerasol. They are corrupt.
