Jim Carrey Slams California School Vaccine Legislation: It's "Poisoning More Children"

Carrey tweeted that Gov. Jerry Brown is a "corporate fascist" who "must be stopped."

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 [sic] 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.

Fellow celebrities have also voiced their displeasure with the law, taking to Twitter to retweet those voicing similar positions and writing their own opinions condemning the compulsory vaccination policy.

Amongst those throwing their weight behind Carrey are Kirstie Alley, who emphasized the "SIXTY-FIVE VACCINES" the law makes mandatory for families and their children. Others, such as fellow Scientologists Jenna Elfman and Danny Masterson, as well as actress Selma Blair and noted activist Erin Brockovich, clarified that though they aren't necessarily anti-vaccine, they feel the law is an egregious case of government overreach and suppression of parental rights.

A petition asking Brown to repeal the law has been gaining steam, with both Blair and Masterson sharing it on Twitter. Thus far, it has nearly reached its goal of 100,000 signatures.

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? — Jim Carrey (@JimCarrey) July 1, 2015

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! — Jim Carrey (@JimCarrey) July 1, 2015

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. — Jim Carrey (@JimCarrey) July 1, 2015

Go to http://t.co/SlY91SQmCj watch the documentary and judge for yourselves. If you really care about the kids you will. It's shocking! — Jim Carrey (@JimCarrey) July 1, 2015

Carrey continued his Twitter diatribe Wednesday morning, insisting he's "pro-vaccine/anti-neurotoxin."

I repeat! I AM PRO-VACCINE/ANTI-NEUROTOXIN, as is Robert Kennedy Jr. Please read the following article and book http://t.co/GTr9lReaXO — Jim Carrey (@JimCarrey) July 1, 2015

All we are saying is,"Take the neurotoxins out of the vaccines." Make them toxin free.History will show that that was a reasonable request. — Jim Carrey (@JimCarrey) July 1, 2015
