Mastercard gives $1.3 billion to boost vaccinations

In one of the largest private sector donations of its kind, the Mastercard Foundation announced it will give $1.3 billion over the next three years to vaccinate 50 million people in Africa. Fewer than 2 percent of the people there have gotten a single dose of the COVID-19 vaccine, far lower than many wealthy countries. Ajay Banga, Mastercard's executive chairman, joins Amna Nawaz to discuss.
