You can have the best vaccines for a woman or her child, but if you can't get her to come and get them then they won't work.

You can't save kids just with vaccines.

Having children made us look differently at all these things that we take for granted, like taking your child to get a vaccine against measles or polio.

We would be driving down the street in a place like Zaire, now the Democratic Republic of Congo, and started to see, my gosh, the only people that have shoes are men. Why does that woman have a baby in her belly and one on her back, and she's carrying a huge load of bananas? You start to ask these questions.

It is still just unbelievable to us that diarrhea is one of the leading causes of child deaths in the world.

So it's an absolute lie that has killed thousands of kids. Because the mothers who heard that lie, many of them didn't have their kids take either pertussis or measles vaccine, and their children are dead today. And so the people who go and engage in those anti-vaccine efforts -- you know, they, they kill children. It's a very sad thing, because these vaccines are important.
