Jessica Biel Insists She's Not an Anti-Vaxxer

Jessica Biel appeared alongside Robert F. Kennedy Jr. to lobby against a California bill that sets new limits on medical exemptions to vaccinations.

Jessica Biel is setting the record straight about her stance on vaccinations.

Biel appeared in Sacramento, California, with Robert F. Kennedy Jr. to lobby against a California vaccination bill that limits medical exemptions this week. 

The 37-year-old actress was all smiles leaving a New York City restaurant with her husband Justin Timberlake Wednesday night, but she tried to set the record straight on Instagram Thursday morning following social media backlash about her appearance with Kennedy.

"I am not against vaccinations - I support children getting vaccinations and I also support families having the right to make educated medical decisions for their children alongside their physicians," she wrote.

"My dearest friends have a child with a medical condition that warrants an exemption from vaccinations, and should this bill pass, it would greatly affect their family's ability to care for their child in this state. That's why I spoke to legislators and argued against this bill."

Kennedy has been a longtime supporter of the anti-vaccination movement. Three of his famous family members recently denounced him in Politico Magazine, saying he "is part of a misinformation campaign that's having heartbreaking — and deadly — consequences."
