Une \u00e9tude du fonds de sant\u00e9 Clalit portant sur l’efficacit\u00e9 du vaccin contre le coronavirus aupr\u00e8s de 1200000 personnes, 600000 ayant re\u00e7u le vaccin et 600000 n’ayant pas \u00e9t\u00e9 vaccin\u00e9es, est devenue la premi\u00e8re \u00e9tude \u00e0 grande \u00e9chelle \u00e0 \u00eatre publi\u00e9e dans une revue \u00e0 comit\u00e9 de lecture mercredi apr\u00e8s sa publication dans le New England Journal of Medicine.<\/strong><\/em><\/p>\n

Bien que l’\u00e9tude ait \u00e9t\u00e9 publi\u00e9e dans les m\u00e9dias isra\u00e9liens au d\u00e9but du mois, elle n’avait pas fait l’objet d’un examen par les pairs mercredi.<\/p>\n

L’\u00e9tude a \u00e9valu\u00e9 l’efficacit\u00e9 du vaccin selon cinq domaines d’int\u00e9r\u00eat: infections au coronavirus confirm\u00e9es par un test PCR, COVID-19 symptomatique, hospitalisation pour COVID-19, cas graves de COVID-19 et d\u00e9c\u00e8s par COVID-19, a rapport\u00e9 le Jerusalem Post.<\/p>\n

Le vaccin contre le coronavirus pr\u00e9vient 57% des cas symptomatiques en environ deux semaines apr\u00e8s la premi\u00e8re dose et 94% des cas symptomatiques sept jours apr\u00e8s la deuxi\u00e8me dose, selon l’\u00e9tude.<\/p>\n

Clalit est le plus grand fonds de sant\u00e9 d’Isra\u00ebl et assure 4,7 millions de patients, soit environ 53% de la population du pays.<\/p>\n

L’\u00e9tude, qui a \u00e9valu\u00e9 les donn\u00e9es de plus d’un million de patients, a \u00e9t\u00e9 l’une des premi\u00e8res \u00e0 examiner l’efficacit\u00e9 du vaccin \u00e0 une si grande \u00e9chelle. La grande quantit\u00e9 de donn\u00e9es d\u00e9taill\u00e9es a \u00e9galement permis aux chercheurs d’estimer l’efficacit\u00e9 du vaccin pour des sous-populations sp\u00e9cifiques, ce que les essais cliniques randomis\u00e9s n’ont pas pu faire. L’efficacit\u00e9 du vaccin s’est av\u00e9r\u00e9e \u00e9lev\u00e9e et similaire \u00e0 l’efficacit\u00e9 rapport\u00e9e dans les essais cliniques.<\/p>\n

Les chercheurs ont constat\u00e9 que pendant la p\u00e9riode de 14 \u00e0 20 jours apr\u00e8s la premi\u00e8re dose, le vaccin \u00e9tait efficace \u00e0 46% pour pr\u00e9venir les infections confirm\u00e9es, 57% efficace pour pr\u00e9venir les cas symptomatiques de COVID-19, 74% efficace pour pr\u00e9venir les hospitalisations, 62% efficace pour pr\u00e9venir maladies graves et 72% efficace pour pr\u00e9venir les d\u00e9c\u00e8s dus aux virus.<\/p>\n

Dans la p\u00e9riode de 21 \u00e0 27 jours apr\u00e8s la premi\u00e8re dose, l’efficacit\u00e9 du vaccin a augment\u00e9, devenant 60% efficace pour pr\u00e9venir les infections confirm\u00e9es, 66% efficace pour pr\u00e9venir les cas symptomatiques de COVID-19, 78% efficace pour pr\u00e9venir les hospitalisations, 80% efficace pour pr\u00e9venir les maladies graves et 84% efficace pour pr\u00e9venir les d\u00e9c\u00e8s dus au virus.<\/p>\n

\u00c0 partir de sept jours apr\u00e8s la deuxi\u00e8me dose, l’efficacit\u00e9 du vaccin s’est nettement am\u00e9lior\u00e9e, pr\u00e9venant 92% des infections confirm\u00e9es, 94% des cas symptomatiques, 87% des hospitalisations et 92% des cas graves. L’\u00e9tude n’a pas d\u00e9termin\u00e9 l’efficacit\u00e9 de la deuxi\u00e8me dose dans la pr\u00e9vention des d\u00e9c\u00e8s dus au virus.<\/p>\n

L’efficacit\u00e9 pr\u00e9sent\u00e9e par l’\u00e9tude Clalit en termes d’hospitalisation, de maladie grave et de d\u00e9c\u00e8s est inf\u00e9rieure \u00e0 l’efficacit\u00e9 pr\u00e9sent\u00e9e par le minist\u00e8re de la Sant\u00e9 en d\u00e9but de semaine, qui rapportait que le vaccin \u00e9tait efficace \u00e0 99% pour pr\u00e9venir ces probl\u00e8mes. En outre, le minist\u00e8re de la Sant\u00e9 a constat\u00e9 que le vaccin \u00e9tait efficace \u00e0 91,8% pour emp\u00eacher les gens de contracter le virus, 96,9% d\u00e9veloppant des sympt\u00f4mes tels que de la fi\u00e8vre et des difficult\u00e9s respiratoires.<\/p>\n
