Le vaccin contre le Covid-19 d\u00e9velopp\u00e9 par les entreprises Pfizer et BioNTech est \u00abtoujours efficace\u00bb apr\u00e8s \u00abtrois doses\u00bb contre le variant Omicron du virus, ont d\u00e9clar\u00e9 ce mercredi 8 d\u00e9cembre les laboratoires, qui souhaitent toutefois finaliser un vaccin adapt\u00e9 \u00abd\u2019ici mars\u00bb. Selon les \u00e9tudes r\u00e9alis\u00e9es par les deux entreprises \u00able vaccin est toujours efficace contre le Covid-19, \u00e9galement contre le variant Omicron, s\u2019il a \u00e9t\u00e9 administr\u00e9 trois fois\u00bb, mais ce variant n\u2019est \u00abprobablement pas suffisamment neutralis\u00e9 apr\u00e8s deux doses\u00bb.<\/p>\n\n\n\n
\u00abNous allons poursuivre le d\u00e9veloppement d\u2019un vaccin sp\u00e9cifique au variant Omicron et esp\u00e9rons le rendre disponible d\u2019ici mars au cas o\u00f9 une adaptation serait n\u00e9cessaire\u00bb, ont indiqu\u00e9 les laboratoires dans un communiqu\u00e9. \u00abUne troisi\u00e8me dose fournit un niveau d\u2019anticorps neutralisants contre Omicron similaire \u00e0 celui observ\u00e9 apr\u00e8s deux doses\u00bb pour les autres variants, ont-ils ajout\u00e9. \u00abBien que deux doses du vaccin puissent encore offrir une protection contre la maladie grave caus\u00e9e par la souche Omicron, il est clair, d\u2019apr\u00e8s ces donn\u00e9es pr\u00e9liminaires, que la protection est am\u00e9lior\u00e9e avec une troisi\u00e8me dose de notre vaccin\u00bb, a r\u00e9sum\u00e9 Albert Bourla, pr\u00e9sident et directeur g\u00e9n\u00e9ral de Pfizer, cit\u00e9 dans un communiqu\u00e9.<\/p>\n\n\n\n
Le variant Omicron consid\u00e9r\u00e9 comme \u00abhautement transmissible par l\u2019OMS\u00bb a \u00e9t\u00e9 d\u00e9tect\u00e9 pour la premi\u00e8re fois fin novembre en Afrique du Sud et a rapidement \u00e9t\u00e9 identifi\u00e9 dans de nombreux pays. Son apparition a provoqu\u00e9 un vent de panique, notamment en Europe, d\u00e9j\u00e0 en proie \u00e0 une massive cinqui\u00e8me vague de cas de Covid-19 provoqu\u00e9s par le variant Delta. Mais il ne semble pas accro\u00eetre la s\u00e9v\u00e9rit\u00e9 des sympt\u00f4mes, selon les derni\u00e8res donn\u00e9es publi\u00e9es par l\u2019OMS. Il est \u00abquasiment certain\u00bb qu\u2019Omicron ne cause pas de cas plus graves que Delta, a ainsi d\u00e9clar\u00e9 mardi \u00e0 l\u2019AFP Anthony Fauci, conseiller de la maison blanche.<\/p>\n\n\n\n
