If you don't have an effective teacher in front of the classroom, you won't change the trajectory for students.

Our economies are built on the backs of all this unpaid labor that women do.

Even in decision-making, we work in self-help groups. That is women coming together in small groups of 10 to sometimes 15 women, where they start to get education about their rights, about clean water and sanitation, about how to have a healthy birth. You can bring in all kinds of education to them that way.

Any social or cultural change has to be made openly and with people agreeing. You don't get there by just pushing an outsider's point of view.

Women are the centre of the family. It's the woman who decides what's eaten in the house, when to have the kids vaccinated; everything that has to do with the children's health revolves around her.

As a woman finds economic opportunity, even if she's only earning a couple of dollars a day, if she can save it on her phone, she then makes different decisions for her household than her husband might.

You can't save kids just with vaccines.
