Malaria Vaccine Via Parasite Injection May Be in the Works
Human challenge trial shows promising results.

The GistMalaria remains one of the most difficult infectious diseases to prevent and treat, particularly in the developing world. However, in a new study, researchers from the United States and the Netherlands may have developed a new weapon against the disease in the form of an injection containing malarial parasites. The findings from the recent study are being presented this week at the American Society of Tropical Medicine and Hygiene's (ASTMH) annual meeting. They indicate for the first time ever that parasite injection results in controlled infection. The procedure holds promise for not only future research but also development of an effective vaccine.
The Expert Take"This study is a great example of the innovative and dynamic research being done through partnerships across academic and corporate sectors that's translating research into needed tools to control and ultimately eradicate malaria," said James Kazura, president of the American Society of Tropical Medicine and Hygiene.
The method of infection used in this study is labeled a "human challenge" trial, in which live human volunteers are injected with parasites rather than exposed to biting mosquitoes.
"What we have here is a new avenue, a new clue to study how the infection develops, and with that we are moving closer to eliminating what is truly a global scourge."
