Can A New Vaccine Put An End To Malaria?

The World Health Organization estimates that every two minutes, a child somewhere in the world dies of malaria. As of 2018, the parasite-induced disease kills a total of more than 400,000 people every year—most of them children under the age of five in sub-Saharan Africa.

While the quest for a malaria vaccine is more than 50 years old, there is still no licensed, fully approved option. The closest to approval, called RTS,S, is being piloted in several countries, with efficacy estimates hovering around 56 percent.

But after a new vaccine, called R21, demonstrated more than 75% efficacy in a small trial in Burkina Faso, is there hope for a more efficient push to reduce the global burden of malaria?

Ira talks to malaria vaccine researcher Prakash Srinivasan and Biden administration malaria coordinator Raj Panjabi about the implications of a vaccine milestone—and the work remaining ahead. Plus, how the COVID-19 pandemic might inform future progress in global health.
