The World Health Organization announced that it has the go-ahead to try the first malaria vaccine in the field in real-world settings next year.

More than 429,000 people lost their lives to the mosquito-borne illness in 2015, and hundreds of millions get sick with a malaria infection every year. Some never fully recover, said CNN. 
There has been enormous progress in fighting the disease. From 2000 to 2015, there was a 62% reduction in malaria deaths, according to the WHO, and a 21% reduction in the number of cases. There have been fewer deaths in large part because of better mosquito control and disease awareness, as well as sustained effort to get the right medicine to the right populations, experts said.
But there are gaps in prevention coverage, particularly in regions such as sub-Saharan Africa, where about 43% of people at risk for the disease don't have access to mosquito protection like bed nets or bug spray, according to the WHO.
Africa is the continent that sees the highest number of malaria cases. The new vaccine will be tested in Kenya, Ghana and Malawi starting in 2018.
Adding a vaccine to the disease-fighting mix could make a significant dent.
"This is great news, actually," said Dr. Photini Sinnis, a deputy director at the Johns Hopkins Malaria Research Institute and professor at Johns Hopkins Bloomberg School of Public Health.

She trained with the GSK scientists who did much of the original research to develop the vaccine in its early days. "At the time, no one thought this would really work. Scientists are skeptical people."
The vaccine, RTS,S, also known as Mosquirix, was created by scientists at GSK in 1987. It was developed in a public-private partnership with the PATH Malaria Initiative and with support from the Bill and Melinda Gates Foundation along with local health organizations from seven African countries. Among the potential malaria vaccines, it is the furthest along.
