Trial overview

Official title: A study to evaluate the safety, immunogenicity and efficacy of GlaxoSmithKline Biologicals’ candidate malaria vaccine RTS,S/AS02A, administered intramuscularly according to a 0, 1 and 2 month vaccination schedule in toddlers and children aged 1 to 4 years in a malaria-endemic region of Mozambique.
Trial description: Malaria is an important cause of death and serious illness among Mozambican children. Although the risk of malaria can be reduced by drugs and by impregnated bed nets, it would be helpful if children could be protected against malaria by a vaccine.
GSK Biologicals is developing in partnership with Malaria Vaccine Initiative at PATH a candidate malaria vaccine RTS,S/AS02 for the routine immunization of infants and children living in malaria endemic areas. The vaccine would offer protection against malaria disease due to the parasite Plasmodium falciparum and also would provide protection against infection with hepatitis B virus. Previous studies have shown the candidate malaria vaccine RTS,S/AS02 to be safe when administered in adults and children aged 1-11 years. However, to assess if this vaccine could provide protection against malaria in children, this study has been undertaken.
