Inexpensive new malaria vaccine is a ‘vital tool’ to protect tens of millions of people



The World Health Organization (WHO) has just recommended a second vaccine to prevent malaria in children, almost exactly two years after it recommended the world’s first.

When given seasonally, the vaccine, called R21/Matrix-M or just Matrix-M, is as effective as the previously recommended vaccine, known as RTS,S or Mosquirix, Tedros Adhanom Ghebreyesus, the director-general of the WHO, said at a news conference on Monday (Oct. 2). In trials conducted in regions where malaria spread seasonally, three doses of Matrix-M cut the rate of symptomatic malaria in the following year by about 75%.
