Variety Breakthrough of the Year Awards

Kristen Bell has a strong message for anti-vaxxers — stay away from my kids!

The Veronica Mars alum – who is mom to daughters Lincoln, 22 months, and 7-week-old Delta – explained her pro-immunization philosophy to The Hollywood Reporter, and revealed she even bans friends from visiting her 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 shared.

The Frozen star is also protecting her newest bundle of joy.

“It’s a very simple logic,” Bell, 34, shared. “I believe in trusting doctors, not know-it-alls.”
