The other big vaccine news
Public-health officials have long sought a vaccine against malaria, which infects up to 600 million people a year and kills 400,000, mostly children. This year, there was dramatic progress toward that goal. In a study of 450 children in Burkina Faso, published in the Lancet in April, researchers reported that a new malaria vaccine, called R21, is 77% effective—just clearing the World Health Organization’s 75% efficacy standard.
However, the sa...
