Kristen Bell , the voice of Frozen 's Anna and the spunky star of House of Lies , believes that parents take the anti-vaccination debate too far and endanger other kids while they are at it . 'Your child is 100 times more likely to be struck by lightning than to have a severe reaction to a vaccine ; that 's a fact , ' Kristen said in an interview for the May issue of Good Housekeeping . The mother of two daughters , Lincoln , two , and Delta , just four months , with actor Dax Sheppard shares how her views on vaccinations actually changed after the birth of her girls , as well as her own self-acceptance of her changing body and the hustle of her acting career .

Citing scientific research , she shares her intimate belief that it 's her duty to not only protect her children , but other children , too - especially those who may suffer from autoimmune diseases or cancer . 'If your kid ca n't get vaccinations ; if he goes to school with my kid and I choose not to give my kid vaccinations , I 'm putting your kid at risk , ' she said . 'To me , that 's unacceptable . ' 'As moms , our responsibility is not just to our kids - it 's to all the other kids , too , ' she added . Kristen adds that being a mother 'right-sized ' her life and has changed her views on more than needles and preventative medicine .
