Jessica Biel isn't the only A-lister with opinions on vaccinations: Celebrity parents who don't vaccinate their children

Jessica Biel has taken a strong stance on vaccinations this week after meeting with legislators in California about the proposed SB276 bill.

The American actress and mum-of-one is petitioning against a new bill which will increase the oversight of doctor’s notes which are currently allowing parents to keep their children from being vaccinated in California.

“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.” She said in an Instagram post.

Jessica, who is married to singer Justin Timberlake, joins a growing number of celebrities who aren’t afraid to speak out about vaccinations.

Alicia Silverstone

Alicia Silverstone has written a whole book about pregnancy and birth.

The book called The Kind Mama: A Simple Guide to Supercharged Fertility, a Radiant Pregnancy, a Sweeter Birth, and a Healthier, More Beautiful Beginning had the following paragraph in:

“While there has not been a conclusive study of the negative effects of such a rigorous one-size-fits-all, shoot-'em-up schedule, there is increasing anecdotal evidence from doctors who have gotten distressed phone calls from parents claiming their child was 'never the same' after receiving a vaccine. And I personally have friends whose babies were drastically affected in this way."
