Global vaccine alliance GAVI said on Wednesday that 12 countries in Africa would receive 18 million doses of malaria vaccine over the next two years, expanding access to the shots to nine new countries in the region.

Malaria remains one of the continent's deadliest diseases, killing nearly half a million children each year under the age of five. In 2021, Africa accounted for about 95 percent of global malaria cases and 96 percent of deaths, according to the World Health Organization.

The nine new countries set to receive the vaccine, developed by British drugmaker GSK, are Benin, Burkina Faso, Burundi, Cameroon, the Democratic Republic of the Congo, Liberia, Niger, Sierra Leone and Uganda

"At least 28 African countries have expressed interest in receiving the RTS,S (malaria) vaccine," WHO chief Tedros Adhanom Ghebreyesus said at a media briefing, adding that a second malaria vaccine was under review for pre-qualification and if successful, could provide additional supply in the short term.

The nine new countries set to receive the vaccine, developed by British drugmaker GSK, are Benin, Burkina Faso, Burundi, Cameroon, the Democratic Republic of the Congo, Liberia, Niger, Sierra Leone and Uganda.
