Africa-Press<\/a> – Burkina Faso<\/a>. <\/strong><\/span>Selon une \u00e9tude men\u00e9e au King’s College de Londres, les vaccins anti-Covid r\u00e9duisent le risque de d\u00e9velopper un Covid long apr\u00e8s l’infection.<\/p>\n

L’\u00e9tude a observ\u00e9 une diminution d’environ 50 % de la persistance des sympt\u00f4mes de Covid pendant plus de quatre semaines chez les personnes qui ont contract\u00e9 la Covid malgr\u00e9 la prise de deux doses du vaccin.<\/p>\n

La plupart des personnes atteintes du Covid se r\u00e9tablissent dans les quatre semaines, mais certaines pr\u00e9sentent des sympt\u00f4mes pendant plusieurs semaines ou mois apr\u00e8s les premi\u00e8res manifestations du Covid-19 – ce que l’on appelle parfois le Covid long.<\/p>\n

Certains peuvent d\u00e9velopper des sympt\u00f4mes b\u00e9nins de covid, bien que la p\u00e9riode de r\u00e9cup\u00e9ration puisse prendre des semaines, voire des mois.<\/p>\n

Dans l’\u00e9tude publi\u00e9e dans la revue m\u00e9dicale The Lancet, les chercheurs affirment que la vaccination s’est av\u00e9r\u00e9e efficace pour pr\u00e9venir la d\u00e9t\u00e9rioration de l’\u00e9tat des personnes infect\u00e9es, mais l’effet des vaccins sur la dur\u00e9e de l’infection n’a pas \u00e9t\u00e9 confirm\u00e9 au m\u00eame degr\u00e9.<\/p>\n

Les chercheurs ont analys\u00e9 les donn\u00e9es collect\u00e9es via l’application Zoe Covid Study, qui suit les sympt\u00f4mes, les vaccins et les tests annonc\u00e9s au Royaume-Uni.<\/p>\n

Cela signifie qu’entre d\u00e9cembre 2020 et juillet dernier, plus de 1,2 million d’adultes qui ont re\u00e7u une seule dose du vaccin et 971 504 de ceux qui ont re\u00e7u deux doses au cours de cette p\u00e9riode ont \u00e9t\u00e9 suivis.<\/p>\n

Les chercheurs ont d\u00e9couvert que seulement 0,2 % de ceux qui ont re\u00e7u les deux doses ont signal\u00e9 une infection par Covid apr\u00e8s la vaccination. Ils ont \u00e9galement observ\u00e9 31 personnes atteintes de COVID-19 long parmi 592 (5 %) qui ont re\u00e7u deux doses du vaccin, puis ont continu\u00e9 \u00e0 fournir des donn\u00e9es sur leurs cas pendant plus d’un mois.<\/p>\n

Parmi les personnes non vaccin\u00e9es, le taux de cette infection \u00e9tait d’environ 11 %.<\/p>\n

Les chercheurs ont d\u00e9couvert que certaines personnes \u00e9taient plus susceptibles que d’autres de contracter le covid apr\u00e8s avoir \u00e9t\u00e9 vaccin\u00e9es – en particulier les personnes \u00e2g\u00e9es et celles vivant dans des zones pauvres.<\/p>\n

C’\u00e9tait \u00e9galement le cas pour les personnes qui ont re\u00e7u une dose unique du vaccin.<\/p>\n

Claire Steves, chef de l’\u00e9quipe de recherche, a recommand\u00e9 que les personnes plus vuln\u00e9rables \u00e0 l’infection que les autres re\u00e7oivent des doses de rappel du vaccin avant les autres.<\/p>\n

Le ministre britannique de la Sant\u00e9, Sajid David, indique que les vaccins ont emp\u00each\u00e9 la d\u00e9t\u00e9rioration de l’\u00e9tat de sant\u00e9 de plus de 105 000 personnes et ont emp\u00each\u00e9 l’infection de plus de 24 millions d’autres rien qu’en Angleterre.<\/p>\n

Jusqu’\u00e0 pr\u00e9sent, 78,9 % ont re\u00e7u le vaccin complet \u00e0 deux doses contre Covid au Royaume-Uni.<\/p>\n","protected":false},"excerpt":{"rendered":"
