As a parent, the responsible thing to do - if you love your child - is to vaccinate your child.

Women and girls should be able to determine their own future, no matter where they're born.

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.

In different places you run into myths around vaccination or around family planning. In the United States, one of the myths that existed for a long time, that has been completely debunked, was that autism was linked to a vaccine.

Sometimes it's the people you can't help who inspire you the most.

If we're going to make progress on this issue [of contraception], we have to be really clear about what our agenda is. We're not talking about abortion. We're not talking about population control. What I'm talking about is giving women the power to save their lives, to save their children's lives and to give their families the best possible future.

If you want to lift up an economy in Africa, you basically start with the women.
