Deutsche Welle: Doubts plague new malaria vaccine

The Guardian: Malaria vaccine a breakthrough despite being partially effective, say scientists
“…The vaccine has been in development for 20 years and has cost more than $500m (£330m) so far.

HealthDay/U.S. News: Malaria Vaccine Shows Promise in Shielding African Children
“…There is currently no vaccine for malaria, and the new vaccine, called RTS,S/AS01, was developed for use in sub-Saharan Africa, where malaria kills about 1,300 children every day. The phase 3 trial of the vaccine included more than 15,400 newborns (ages six to 12 weeks at first vaccination) and children (five to 17 months at first vaccination) at 11 sites in seven sub-Saharan African countries…” (Preidt, 4/23).

Reuters: World’s first malaria vaccine moves closer to use in Africa

Wall Street Journal: Problems Found With Glaxo’s Malaria Vaccine
