Apr\u00e8s des inqui\u00e9tudes apparues autour de l\u2019efficacit\u00e9 du vaccin Oxford-AstraZeneca contre le Covid-19, les autorit\u00e9s sud-africaines ont d\u00e9cid\u00e9 de vendre leurs 1,5 million de doses aux pays africains qui se sont montr\u00e9s int\u00e9ress\u00e9s.<\/strong><\/p>\n

Des inqui\u00e9tudes quant \u00e0 l\u2019efficacit\u00e9 du vaccin \u00e0 partir d\u2019une petite \u00e9tude<\/h2>\n

L\u2019Afrique du Sud avait obtenu 1,5 million de doses du vaccin contre le Covid-19 de l\u2019Universit\u00e9 d\u2019Oxford-AstraZeneca pour sa population.<\/p>\n

Il y a un mois, le m\u00e9dicament s\u2019est envol\u00e9 du Serum Institute of India et un lot d\u2019un million de vaccins a \u00e9t\u00e9 re\u00e7u par le pr\u00e9sident Cyril Ramaphosa et le ministre de la sant\u00e9, le Dr Zweli Mkhize, en personnes. Le pays attendait une autre livraison de 500 000 doses.<\/p>\n

Celles-ci \u00e9taient cens\u00e9es \u00eatre administr\u00e9es en priorit\u00e9 aux professionnels de la sant\u00e9 et aux travailleurs de premi\u00e8re ligne.<\/p>\n

Mais c\u2019\u00e9tait avant que des inqui\u00e9tudes n\u2019apparaissent quant \u00e0 l\u2019efficacit\u00e9 du vaccin sur le variant sud-africain.<\/p>\n

Une petite \u00e9tude men\u00e9e par l\u2019universit\u00e9 de Witwatersrand \u00e0 Johannesburg<\/a> a soulign\u00e9 que le vaccin Oxford-AstraZeneca avait une efficacit\u00e9 limit\u00e9e contre les sympt\u00f4mes l\u00e9gers et mod\u00e9r\u00e9s<\/strong> caus\u00e9s par le variant dominant dans le pays.<\/p>\n

Les essais ont \u00e9t\u00e9 men\u00e9s sur 2 000 personnes dont l\u2019\u00e2ge m\u00e9dian \u00e9tait de 31 ans. Les r\u00e9sultats pr\u00e9liminaires publi\u00e9s le 7 f\u00e9vrier n\u2019ont pas encore \u00e9t\u00e9 examin\u00e9s par des pairs. De plus, l\u2019efficacit\u00e9 n\u2019a pas \u00e9t\u00e9 test\u00e9e sur les formes graves du variant B.1.351\u202fen raison de la petite taille de l\u2019\u00e9chantillon. \u00ab\u202fLa protection contre la maladie mod\u00e9r\u00e9ment grave, l\u2019hospitalisation ou la mort n\u2019a pas pu \u00eatre \u00e9valu\u00e9e dans cette \u00e9tude car la population cible \u00e9tait \u00e0 risque faible<\/em>.\u202f\u00bb<\/p>\n

Le 10 f\u00e9vrier 2021, l\u2019OMS a publi\u00e9 des recommandations provisoires<\/a> et a pr\u00e9conis\u00e9 l\u2019utilisation du vaccin \u00ab\u202fm\u00eame si des variants sont pr\u00e9sents dans un pay<\/em>s\u202f\u00bb.<\/p>\n

Cependant, l\u2019Afrique du Sud a d\u00e9cid\u00e9 de ne pas l\u2019utiliser du tout.<\/p>\n

\"D\u00e9claration
D\u00e9claration du ministre sud-africain de la Sant\u00e9 sur le vaccin d\u2019Astrazeneca<\/figcaption><\/figure>\n

Des pays africains int\u00e9ress\u00e9s par le vaccin<\/h2>\n

<\/p>\n

Le ministre de la sant\u00e9 a ensuite d\u00e9clar\u00e9 au parlement que les doses seraient distribu\u00e9es aux membres de l\u2019Union africaine<\/a> qui se montrent int\u00e9ress\u00e9s par le stock.<\/p>\n

Certains pays africains sont en effet moins touch\u00e9s par le variant sud-africain et n\u2019h\u00e9sitent pas \u00e0 b\u00e9n\u00e9ficier des protections de ce vaccin.<\/p>\n

Sarah Gilbert, professeure de vaccinologie \u00e0 l\u2019universit\u00e9 d\u2019Oxford, a d\u00e9clar\u00e9 \u00e0 la BBC<\/a> qu\u2019ils travaillaient sur une nouvelle version du vaccin qui \u00ab\u202fg\u00e9n\u00e8re des anticorps qui reconnaissent le nouveau variant<\/em>\u202f\u00bb. \u00ab\u202fIl semble tr\u00e8s probable qu\u2019il sera pr\u00eat \u00e0 \u00eatre utilis\u00e9 \u00e0 la fin de l\u2019automne<\/em>\u202f\u00bb. Elle pense \u00e9galement que la version actuelle offre un certain degr\u00e9 de protection contre le variant provenant d\u2019Afrique du Sud.<\/p>\n

Le 21 mars 2021, le pays a d\u00e9clar\u00e9 qu\u2019un premier lot avait \u00e9t\u00e9 achet\u00e9 par 9 \u00c9tats membres de l\u2019UA. Le reste sera vendu \u00e0 5 autres pays.<\/p>\n

Le gouvernement sud-africain a assur\u00e9 que la date d\u2019expiration n\u2019\u00e9tait pas encore d\u00e9pass\u00e9e. Selon News24<\/em>, le pays allait vendre le vaccin au m\u00eame prix qu\u2019il l\u2019avait achet\u00e9.<\/p>\n

Par mesure de pr\u00e9caution, plusieurs membres de l\u2019Union europ\u00e9enne ont r\u00e9cemment interrompu le d\u00e9ploiement du vaccin Oxford-Astrazeneca<\/a> pendant quelques jours en raison d\u2019inqui\u00e9tudes li\u00e9es \u00e0 des probl\u00e8mes de coagulation sanguine. Ils ont repris les inoculations quelques jours plus tard, mais la confiance dans la s\u00e9curit\u00e9 du vaccin a diminu\u00e9.<\/p>\n

La R\u00e9publique d\u00e9mocratique du Congo, le Mali et le Cameroun avaient \u00e9galement suspendu les injections en r\u00e9action \u00e0 la d\u00e9cision de l\u2019UE.<\/p>\n

L\u2019Afrique du Sud est le pays le plus touch\u00e9 par la pand\u00e9mie de Covid-19\u202fen Afrique avec 1,54 million de cas d\u00e9clar\u00e9s et 52 000 d\u00e9c\u00e8s signal\u00e9s.<\/p>\n
