On several occasions, “Dumb and Dumber” star Jim Carrey has publicly expressed his disdain for vaccines, especially when it comes to vaccinating children. In 2009, he wrote a HuffPost essay objecting to child vaccines due to perceived links to autism, per Insider. HuffPost has since removed that essay from their platform amid the COVID-19 pandemic, citing interest to the public health, but that hasn’t stopped Carrey.
In 2008, the “Liar Liar” star spearheaded the “Green Our Vaccines” march on Washington D.C., per ABC News, with the stated goal of removing toxins from children’s vaccines. What toxins, you ask? In 2015, in a series of tweets, he denounced California Gov. Jerry Brown for signing into law mandatory vaccines, per TIME, writing he was concerned about “mercury and aluminum in manditory [sic] vaccines.” Carrey subsequently tweeted, “They say mercury in fish is dangerous but forcing all of our children to be injected with mercury in thimerosol [sic] is no risk.” He followed those with, “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!” A year later, Carrey was still tweeting “save our kids” when it came to vaccines.
The CDC and health practitioners have repeatedly reported on the efficacy of vaccines, how there’s no evidence to support the view that vaccines cause autism, and that thimerosal doses in vaccines are so low that health risks are minimal.
