Cameroon has started giving a regular vaccine for malaria to children. This is the first time this has been done in the world. It is expected to save many children's lives in Africa. A baby girl named Daniella got her first vaccine at a health center near Yaoundé on Monday. This is an important step to help keep her healthy. Every year, 600,000 people in Africa die from malaria, according to the World Health Organization (WHO). At least 80% of the people who die are children under five years old. Cameroon is giving the RTS,S vaccine for free to all babies up to six months old. Patients need to take four doses in total. According to US researchers, the jab works in at least 36% of cases and could save more than one in three lives. The rollout is a relief and helps save lives, but it doesn't work great, according to Willis Akhwale at End Malaria Council Kenya. But doctors say it is an important tool to help fight malaria. Shalom Ndoula, a doctor from Cameroon, helped introduce this tool in his country. "We can greatly reduce the number of malaria cases and deaths and speed up getting rid of the disease," he said in an interview with the BBC. It took 30 years for the British drug-maker GSK to research and develop the RTS,S vaccine. The World Health Organization said the vaccine is good and they are happy that it is being used in Cameroon to fight against a disease spread by mosquitoes. They think this is a very important moment in the world's fight against the disease. It happens after test campaigns in Kenya, Ghana and Malawi were successful. Twenty more countries plan to start the programme this year, according to the global vaccine alliance, Gavi. Some of the countries are Burkina Faso, Liberia, Niger, and Sierra Leone. The WHO says that in Cameroon, there are about six million cases of malaria every year. About 4,000 people die from malaria in hospitals, and most of them are children under five years old. Babies who are six months old and live in 42 areas with the highest rates of sickness and death will get four doses of medicine before they turn two years old. In 2021, most of the malaria cases and deaths in the world happened in Africa.
