L’Organisation Mondiale de la Sant\u00e9 autorise un deuxi\u00e8me vaccin contre le paludisme, \u00e0 destination des enfants. Le R21-Matrix-M est d\u00e9sormais valid\u00e9 par l’OMS. Une d\u00e9cision qui ouvre la porte \u00e0 une plus grande diffusion de ce vaccin, alors que jusqu’\u00e0 pr\u00e9sent, seuls trois pays africains le recommandaient.<\/strong><\/p>\n\n\n\n

En 2021, le paludisme avait tu\u00e9 plus de 600 000 personnes dans le monde. L’Afrique concentre l’\u00e9norme majorit\u00e9 des cas et parmi les victimes sur le continent, ce sont les enfants de moins de cinq ans qui sont particuli\u00e8rement touch\u00e9s. C’est pour cette raison que depuis des ann\u00e9es, les efforts se sont concentr\u00e9s sur le d\u00e9veloppement d’un vaccin p\u00e9diatrique.<\/p>\n\n\n\n

Le patron de l\u2019OMS, le Dr Tedros, ne cachait pas sa joie au moment d\u2019annoncer la validation du vaccin R21\/Matrix-M. \u00ab Depuis l\u2019an 2000, le nombre de morts du paludisme a chut\u00e9 de plus de 50 %. Et nous avons r\u00e9ussi \u00e0 \u00e9liminer la maladie dans de nombreux endroits sur la plan\u00e8te. Mais depuis, nous stagnons. Moi-m\u00eame, en tant qu\u2019ancien chercheur sur le sujet, j\u2019ai r\u00eav\u00e9 du jour o\u00f9 nous aurions un vaccin s\u00fbr et efficace contre la maladie. Et bien aujourd\u2019hui, nous en avons deux. <\/em>\u00bb   <\/p>\n\n\n\n

Apr\u00e8s le RTS-S recommand\u00e9 il y a deux ans, c’est donc le R21-Matrix-M qui re\u00e7oit le label de l’OMS ce mardi, avec 77% d’efficacit\u00e9 av\u00e9r\u00e9e selon les \u00e9tudes. Sur le papier, cela peut changer la donne face \u00e0 la maladie.<\/p>\n\n\n\n

Le premier vaccin autoris\u00e9 a en effet fait ses preuves, avec une efficacit\u00e9 similaire. L’OMS a observ\u00e9 une diminution importante des formes graves et mortelles du paludisme l\u00e0 o\u00f9 il est administr\u00e9. Mais la demande d\u00e9passe aujourd’hui largement l’offre.<\/p>\n\n\n\n

D’o\u00f9 l’int\u00e9r\u00eat de mettre un second produit \u00e0 disposition. Tout l’enjeu repose d\u00e9sormais sur son accessibilit\u00e9. Il avait d\u00e9j\u00e0 \u00e9t\u00e9 autoris\u00e9 dans trois pays : au Ghana, au Nigeria, et au Burkina Faso. Cette recommandation de l’Organisation mondiale de la sant\u00e9 devrait donc faciliter sa large diffusion.<\/p>\n\n\n\n

D’autant que la capacit\u00e9 de production pour ce second vaccin est importante. GSK, qui fabrique le RTS-S, compte livrer 18 millions de doses \u00e0 12 pays africains d\u2019ici 2025. Le R21\/Matrix-M, lui, a l\u2019avantage d\u2019\u00eatre d\u00e9velopp\u00e9 par le Serum Institute of India. Le plus grand fabricant de vaccins au monde. 100 millions de doses devraient sortir des usines indiennes chaque ann\u00e9e.<\/p>\n\n\n\n

\n

Les publications qui ont \u00e9t\u00e9 faites avec le nouveau vaccin \u00e9taient tout \u00e0 fait favorables, avec une capacit\u00e9 de protection qui \u00e9tait de l’ordre de 70%, qui \u00e9tait bien sup\u00e9rieur au 30 et quelque % du vaccin pr\u00e9c\u00e9dent, gr\u00e2ce sans doute \u00e0 ce booster d’efficacit\u00e9 protectrice par cette substance ajout\u00e9e au vaccin.<\/em><\/p>\n\n\n\n
