What Plasmodium organism is Raymond G. Chambers an envoy for?
Malaria Malaria is a mosquito-borne infectious disease affecting humans and other animals caused by parasitic protozoans (a group of single-celled microorganisms) belonging to the "Plasmodium" type. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases it can cause yellow skin, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria.
RTS,S RTS,S/AS01 — trade name Mosquirix — is a recombinant protein-based malaria vaccine. Approved for use by European regulators in July 2015, it is not only the world's first licensed malaria vaccine, but the first vaccine licensed for use against a parasitic disease of any kind. The RTS,S vaccine was conceived of and created in the late 1980s by scientists working at SmithKline Beecham Biologicals (now GlaxoSmithKline Vaccines) laboratories in Belgium. The vaccine was further developed through a collaboration between GSK and the Walter Reed Army Institute of Research and has been funded in part by the PATH Malaria Vaccine Initiative and the Bill and Melinda Gates Foundation. Its efficacy ranges from 26 to 50% in infants and young children. It is considered to be a milestone advance in the worldwide campaign against malaria. On 23 October 2015, The World Health Organization's Strategic Advisory Group of Experts on Immunization (SAGE) and the Malaria Policy Advisory Committee (MPAC) jointly recommended a pilot implementation of the vaccine in Africa.
