Why Jessica Biel Says She's Actually Not Anti-Vaxx

Jessica Biel claims she's not against vaccinations -- but simply supports a family's right to choose to opt out of getting them.

Just one day after "The Sinner" star received major backlash for talking to state legislators with Robert F. Kennedy Jr, a known anti-vaxx activist, Biel took to Instagram to clarify her stance on vaccinations and explain why she opposes SB 276, a state bill that would limit medical exemptions from vaccinations.

"This week I went to Sacramento to talk to legislators in California about a proposed bill," she captioned a shot of her in front of the state capitol. "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. My concern with #SB277 is solely regarding medical exemptions."

The "7th Heaven" alum pointed out she has a personal connection to someone who she claims would be negatively impacted by the proposed bill.

"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," Biel said. "That's why I spoke to legislators and argued against this bill. Not because I don't believe in vaccinations, but because I believe in giving doctors and the families they treat the ability to decide what's best for their patients and the ability to provide that treatment."

She added, "I encourage everyone to read more on this issue and to learn about the intricacies of #SB277. Thank you to everyone who met with me this week to engage in this important discussion!"

However, many people ripped the actress in the comments section, claiming her views on vaccines would cause harm to others, including their own children.

"If a child isn't vaccinated, they shouldn't be allowed into the schooling system," a person wrote. "If you want parents to have the right to choose, that's fine, but those same kids shouldn't have the right to put others in danger because of their parents' idiocy."

"Don't get involved in science you don't understand. Vaccinations impt and you are confusing people," a user added and another said, ""My son has a rare progressive genetic disease, and someone who is not vaccinated could give him an infection that could kill him. Consider all sides please."

On the other hand, anti-vaxx activists praised Biel for taking a stand on the controversial issue.

"Thank you! My family carries the MTHFR mutation! We definitely are a non vaccine family," a person commented. "My husband developed Type 1 diabetes because of the MMR shot! Not a risk I am willing to take! Be brave and don't listen to the uninformed programmed BULLYING!"

Another added, "Thank you for being brave and standing up on such an important issue that effects so many families across our Nation."

Biel's post comes one day after Kennedy shared photos of him and Biel. speaking out against the proposed bill.

"Please say thank you to the courageous @jessicabiel for a busy and productive day at the California State House," he captioned the post, below.

Biel has never confirmed her views on vaccinations when it comes to her child, Silas, 4, who she shares with husband Justin Timberlake. However, back in 2015 rumors circulated Biel and Timberlake weren't planning on vaccinating Silas.

"She feels that vaccination could cause complications," a source told In Touch Weekly at the time.
