(Reuters) – The world’s first potential malaria vaccine proved only 30 percent effective in African babies in a crucial trial, calling into question whether it can be a useful weapon in the fight against the deadly disease.
The surprisingly poor result for the vaccine, which GlaxoSmithKline has been developing for three decades, leaves several years of work ahead before a protective malaria shot could be ready for countries that desperately need one.
Malaria, a mosquito-borne parasitic disease, kills hundreds of thousands a year, mainly babies in Africa, and scientists say an effective vaccine is key to hopes to eradicate it.
Philanthropist Bill Gates, who helped fund the GSK vaccine’s development, said further research was now needed to see whether and how it might be used.
“The efficacy came back lower than we had hoped, but developing a vaccine against a parasite is a very hard thing to do,” he said in a statement.
