The vaccine trials have yielded remarkable results demonstrating that RTS,S, alongside antimalarial drugs before the rainy season, reduced severe malaria cases and deaths by nearly two thirds. Children who received the RTS,S drug combination and used bed nets had a greater than 90% protection against malaria episodes during the study.<\/b><\/p>\n<p>As the first-ever childhood malaria vaccination programme begins we highlight the story behind the headlines. Monday 22 January 2024 saw the rollout of the world\u2019s first malaria vaccine, RTS,S, in Cameroon with over 6.6 million children expected to receive the vaccine in 20 African countries over the next two years. The start of routine RTS,S vaccinations for malaria, organised by Gavi, WHO and UNICEF, has only been possible following decades of work by researchers in Africa working with international partners including MRCG at LSHTM. Professor Umberto D\u2019Alessandro, Director of MRCG at LSHTM, said: \u201cMaking the RTS,S vaccine available as a routine vaccination is only possible thanks to decades of work by researchers in Africa working with international partners, with clinical trials at MRCG at LSHTM starting back in 1997. The support of volunteers and communities both in The Gambia and the region has been vital in showing that RTS,S, the world\u2019s first malaria vaccine, is safe and can save lives. The support of volunteers and communities both in The Gambia and the region has been vital in showing that RTS,S, the world\u2019s first malaria vaccine, is safe and can save lives.\u201d The support of volunteers and communities both in The Gambia and the region has been vital in showing that RTS,S, the world\u2019s first malaria vaccine, is safe and can save lives. The support of volunteers and communities both in The Gambia and the region has been vital in showing that RTS,S, the world\u2019s first malaria vaccine, is safe and can save lives.\u201d The Phase I trial, conducted between 1997-1998, showed vaccine safety. This paved the way for subsequent Phase II studies, conducted in infants and children across The Gambia and other endemic countries, which established the efficacy of RTS,S for reducing morbidity due to clinical malaria. The final Phase III trial (2009-2014) involved 15,459 infants and young children across seven African countries, preventing approximately 39% of malaria cases and 29% of severe malaria cases over four years. A LSHTM-coordinated trial since 2017 immunised over 5,000 children in Burkina Faso and Mali. Dr Kalifa Bojang, Senior Clinical Scientist at MRCG at LSHTM, underscored the Unit\u2019s commitment to eradicating malaria and its pivotal role in early RTS,S development, he said: \u201cFrom clinical trials in The Gambia to subsequent trials that demonstrated the impact of RTS,S on reducing severe malaria cases and child mortality, MRCG at LSHTM remains a beacon of hope in the global pursuit of a malaria-free future.\u201d RTS,S is the first malaria vaccine recommended by WHO to prevent malaria in children (October 2021). It induces an immune response to the circumsporozoite protein antigen found on the surface of the Plasmodium falciparum sporozoite, the stage of the parasite which is injected by a mosquito. WHO has recommended a schedule of four doses in children from around 5 months of age, with a fifth dose considered after one year in areas of high risk. RTS,S was initially developed by GSK and the PATH Malaria Vaccine Initiative (MVI). A second vaccine, R21, developed by Oxford University received approval from WHO in 2023 using lessons learned RTS.S<\/p>\n<p><strong>For More News And Analysis About <a href=\"https:\/\/www.africa-press.net\/gambia\">Gambia<\/a> Follow <a href=\"https:\/\/www.africa-press.net\/\">Africa-Press<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Africa-Press &#8211; Gambia.
