Malaria: Best Vaccine Yet

The long-awaited RTS,S/AS01 malaria vaccine may be available as early as October after final trial results showed it is partially effective against the disease in African children up to 4 years after vaccination.

Findings published in the Lancet showed its effectiveness waned over time but could be improved with a booster dose, said Brian Greenwood, corresponding author and a professor at London School of Hygiene & Tropical Medicine.

Greenwood noted that in 3 years of follow-up, an average of 558 cases were averted for every 1,000 infants vaccinated, and 983 cases in those given a booster dose.

Initial phase 3 results released last year revealed vaccine efficacy of about 46% against clinical malaria in children and around 27% among young infants, suggesting that millions of malaria cases in children can be averted.
