Kristen Bell has no patience whatsoever for anti-vaxxers, and will not allow them near her kids.

The actress and husband Dax Shepard have two children - Lincoln, 22 months, and Delta, born in December 2014. Kristen is so pro-immunization (also known as having basic common sense), friends are not allowed near their newborn unless they are up to date with their own shots.

"When Lincoln was born (in March 2013), the whooping cough epidemic was growing, and before she was 2 months old, we simply said, 'You have to get a whooping cough vaccination if you are going to hold our baby,'" she told the Hollywood Reporter. "It's a very simple logic. believe in trusting doctors, not know-it-alls."

Know-it alls? Jenny McCarthy, we're looking at you, jackass.

Considering diseases that were all but eradicated are making a comeback, hurting children who can't be immunized or are too young to get their shots, it's safe to say the anti-vaxx looneys have a LOT to answer for.
