New malaria vaccine to be used in Ghana
Oxford University has developed a new malaria vaccine that is said to provide up to 77% protection against the disease. Ghana is the first country to approve this vaccine, and the university is hoping that more countries will follow suit in the future to save more lives.
The vaccine is most effective when it is given to children between 5 months and 3 years old, when they are most at risk of dying from the disease.
The difficulty in developing an effective malaria vaccine is due to the fact that the malaria parasite changes form during its life cycle. Researchers have to decide which stage of the parasite's life cycle the vaccine should target in order to be effective.
