New malaria vaccine results raise hopes of mass rollout
A booster dose of a new malaria vaccine maintains a high level of protection against the disease, researchers said Thursday, expressing hopes the cheap jab could be produced on a massive scale in a matter of years.. For the group that received the higher dose of adjuvant, the booster rose the protection level to 80 percent, according to the results of a phase 2b trial published in The Lancet Infectious Diseases journal on Thursday.
