 Plasmodium Information - October 7, 2008
| Researchers at the National Institute of Standards and Technology (NIST) are using radiation science to create weakened, harmless versions of a parasite to create a new type of vaccine that shows promise of being more effective than current malaria vaccines. The new vaccine is a departure from previous approaches, which have usually depended on proteins derived from only part of the parasite Plasmodium falciparum, the most dangerous species of parasite that causes malaria | | A new company is developing malaria vaccines from mosquitoes. Researchers of Sanaria Inc. are feeding mosquitoes human blood contaminated with the parasite Plasmodium falciparum | | An experimental malaria vaccine tested in infants in Mozambique, Africa is safe and effective in babies, a new research has found. Scientists tested the drug in 214 infants, from ages 10-18 and compared the results to those who were not vaccinated. The drug reduced the number of new infections in the infants by 65 percent, in a three month period, it was found. Investigators say the vaccine also reduced the number of infants who became critically ill by 35 percent | | International researchers have successfully tested the effectiveness of a new anti-malaria vaccine on African babies. They will proceed to the final stage of the clinical trial of RTS,S in the hope that the vaccine will be approved by the medical community for use in protecting people against the deadly mosquito-borne disease. According to Agence France-Presse, results of the latest clinical tests of the RTS,S were contained in a study released on Wednesday. The study, published in the British health journal The Lancet, said the tests involved the vaccination of 214 infants from malaria-infested villages in Mozambique with the vaccine developed by GlaxoSmithKline Biologicals of Belgium two decades ago and a standard hepatitis B vaccine called Engerix-B | | Scientists at the Johns Hopkins University in Baltimore, U.S. hope to take a giant step towards eradicating malaria with the development of a genetically-engineered mosquito designed to resist infection by malarial parasites. The test mosquitoes have been spliced with an extra gene which prevents them from transmitting Plasmodium berghei, one of the common malarial parasites. Malaria currently kills up to three million people throughout the world annually, most of the them small children | |
