A vaccine that protects against malaria by 50% – a reality
Vaccine that reduces the chance of contracting malaria by nearly 46% in 15 months, will save hundreds of lives, say scientists. Despite the fact that the new vaccine does not provide absolute protection from parasites, provoking disease development looks very promising, writes The Telegraph.
During Phase II clinical trial of 447 children in Kenya and Tanzania, aged five to 17 months of receiving the vaccine, called RTS, S/AS01E. At the same time similar to the control group received the vaccine against rabies.
After fifteen months, the scientists saw: children vaccinated against malaria, 46% less likely to become infected by the parasite P. Falciparum compared to the control group. Only in 11.4% of children in the first group was marked clinical form of malaria. In the control group the figure equaled 19.7%.
Commented research director Dr. Ellie Olot of the Kenya Medical Research Institute: "The vaccine provides persistent protection for at least fifteen months. There is every reason to believe that its introduction in the vaccination program of children in affected countries may be possible . vaccine works by attacking the parasite when he first enters the bloodstream or liver cells. goal – to completely prevent infection of red blood cells ". p>
Shortly professionals want to test the effectiveness of the vaccine on children and malnourished patients with HIV . These two problems and malaria are critical for the African region.
