Kristen Bell bans friends from holding baby unless vaccinated

Vaccinations have become a big hot button debate, especially among parents.

Now, actress Kristen Bell is weighing in.

She says she won't let anyone hold her kids unless they are vaccinated.

Bell and actor Dax Shepard just welcomed their second daughter Delta in December. They also have a 22 month-old daughter named Lincoln.

She's been very vocal about her pro-immunization philosophy and policy.

"It's very simple logic. I believe in trusting doctors, not know-it-alls," she said.

She says anyone who wants to come close to her kids, including friends and family, must be up-to-date on their whooping cough and measles vaccinations.
