Future or Investigational Therapies
Anti-Malaria Vaccine
In October 2005, Malaria Vaccine Initiative PATH (MVI/PATH) partnered with Glaxosmithkline, a pharmaceutical company, to develop an anti-malaria vaccine, using a grant by Bill & Melinda Gates Foundation.
The vaccine, called "GSK RTS,S/AS01" was administered with other vaccines included in Expanded Programme on Immunization (EPI). It includes 2 proteins: RTS and S. It is produced by S. cerevisiae species. The project ended in December 2014 with the publishing of two phase 3 trial reports in 2011 and 2012. The "RTS,S/AS01" vaccine affects the pre-erythrocytic stage of "P. falciparum" in young (5-17 months old) African children.[1] The authors concluded in 2011, after 12 months of follow-up, that the candidate vaccine has an efficacy against clinical and severe malaria of 55.8% and 47.3%, respectively.[1] In cases of severe malaria in children between 6 to 12 weeks of age, the efficacy was less. In 2012, infants 6-12 weeks of age were enrolled. The study showed that the vaccine efficacy against all clinical malaria was 32.9% and against severe malaria was 29%.[1]
