Celeb: That British accent, that no-nonsense demeanor — it’s Jo Frost, the nanny turned child-care expert and author who starred in the former ABC show “Supernanny.”

Cause: Childhood vaccinations across the globe, led by the U.N. Foundation’s Shot@Life program. Frost has no truck with the anti-vaxxers who’ve been the focus of media attention lately. “As parents, we have a responsibility to make sure that our children are protected from fatal disease,” she said. “Vaccinations are a must.”

Scene: Frost bent ears on the Hill on Tuesday alongside more than 100 other volunteers, visiting the offices of Reps. John Yarmuth (D-Ky.), Dave Price (D-N.C.) and Sen. Mark Kirk (R-Ill.).

She didn’t even have to resort to her famous “time-out” chair during her first-ever visit to Capitol Hill — she said the lawmakers were receptive and eager to learn more. “They wanted numbers and statistics, which is music to my ears,” she said. “Getting accurate information out there on this issue is crucial.”

But vaccinations weren’t the only topic of discussion. She said that all day, staffers and other folks she met with had been pulling her away for sidebars, seeking advice on dealing with misbehaving toddlers and the like. “It doesn’t matter if you’re a journalist or a congressman or staff, everyone’s someone’s family,” she said.

Soundbite: “Education equals empathy and us all looking after each other. It’s not about ‘my child’s okay, and that’s enough.'”
