Brits Develop New Vaccine To Cure Malaria!
Malaria: Brits Develop New Vaccine!
Malaria is a terrible disease that killed 650,000+ worldwide in 2010 and until now, there's been little hope for a cure or an effective vaccine. But scientists in Britain have recently developed a vaccine which they say releases an antibody that halts many strains of the P. falciparum parasite, spread by mosquitos, that cause the disease. It's been tested with great success on mice and rabbits.
How the Malaria Vaccine Works...
The vaccine targets a single receptor for a protein called RH5. That's the one that allows the parasite to enter the blood stream and spread and multiply. Dr Sandy Douglas, author of the study, said, "It is an important step towards developing a much-needed vaccine against one of the world's major killers."
Previously, research had proved to be trying because the parasites' antigens were too genetically varied--and that's why the RH5 is different--it's not!
New Malaria Vaccine: Hope for the World!
Although there is an existing, experimental vaccine for Malaria, scientists say it doesn't go far enough. Furthermore, the existing vaccine attempts to restrict the parasite from entering the liver, while the RH5 vaccine targets the parasite in the blood. However, there may be a possibility that the two vaccines may complement each other, which would be most encouraging.
The RH5 vaccine is due to be tested on humans in about three years, however, it's doubtful that it will be available for approximately 10 years.
