\n D\u00c9CRYPTAGE –<\/strong> Les r\u00e9sultats montrent que le vaccin Pfizer \u00e0 ARNm est 34,5\u00a0% plus efficace que son homologue. Mais il reste un long chemin avant qu\u2019il s\u2019impose…<\/p>\n

Bient\u00f4t un vaccin \u00e0 ARN messager contre\u00a0la grippe<\/a>\u00a0? Toutes les entreprises pharmaceutiques qui se sont d\u00e9marqu\u00e9es avec cette technologie pendant la pand\u00e9mie de Covid-19 sont sur le coup. Plus faciles et\u00a0plus rapides \u00e0 fabriquer que les vaccins \u00ab classiques\u00a0\u00bb<\/a>, les\u00a0vaccins \u00e0 ARNm<\/a>\u00a0pourraient \u00eatre tr\u00e8s avantageux pour lutter contre la grippe. Encore faut-il prouver leur efficacit\u00e9… Une \u00e9tude r\u00e9cemment publi\u00e9e dans le New England Journal of Medicine montre que l\u2019affaire est en bonne voie pour la firme am\u00e9ricaine Pfizer. Son candidat vaccin se r\u00e9v\u00e8le \u00eatre au moins aussi efficace, voire plus qu\u2019un vaccin habituel.<\/p>\n

Ces deux types de produits ont le m\u00eame objectif\u00a0: apprendre au syst\u00e8me immunitaire \u00e0 combattre les virus grippaux. En revanche, leur composition est tr\u00e8s diff\u00e9rente. Les vaccins conventionnels contre la grippe contiennent des virus ou des fragments de virus rendus inoffensifs. Le vaccin \u00e0 ARN consiste, lui, \u00e0 injecter la \u00ab\u00a0notice d\u2019assemblage\u00a0\u00bb d\u2019\u00e9l\u00e9ments du virus\u2026<\/p>\n
