Abstract
Have you ever heard of malaria? It is a serious illness spread by mosquito bites and affects millions of people every year. Scientists have developed vaccines to help stop malaria. The new R21 vaccine seems very promising. We tried it in 5,139 children in Africa to see if it works and if it is safe.
We discovered that the vaccine worked very well. Avoid 73% of malaria cases in general. It worked better for younger children, stopping 78% of cases. In addition, most of the side effects were mild, such as an arm or fever pain, and serious problems were rare.
This vaccine could help save many lives if used more widely in places where malaria is common.
