Bonne nouvelle : le vaccin contre le Covid-19 pourrait non seulement prot\u00e9ger des formes graves, ce qui est d\u00e9j\u00e0 largement prouv\u00e9, mais \u00e9galement emp\u00eacher \u00e0 la personne vaccin\u00e9e de porter le virus et de le transmettre \u00e0 son entourage. Plusieurs \u00e9tudes r\u00e9centes vont dans ce sens. La derni\u00e8re en date, r\u00e9alis\u00e9e au Royaume-Uni, montre qu’une seule dose du vaccin Pfizer-BioNTech ou d’AstraZeneca r\u00e9duit drastiquement les risques de contamination au sein d’un foyer.<\/div>\n
R\u00e9alis\u00e9e par le Public Health England (PHE), l’\u00e9tude a suivi 57.000 personnes issues de 24.000 m\u00e9nages. Dans chacun de ces m\u00e9nages, au moins une personne vaccin\u00e9e contre le Covid-19 a \u00e9t\u00e9 test\u00e9e positive au SARS-CoV-2, le virus responsable du Covid-19. Les chercheurs ont compar\u00e9 ce groupe \u00e0 pr\u00e8s d’un million de contacts de personnes non vaccin\u00e9es. Au final, les personnes infect\u00e9es par le virus trois semaines apr\u00e8s avoir re\u00e7u une dose de vaccin \u00e9taient 38% \u00e0 49% moins susceptibles de transmettre le virus aux autres membres de leur foyer que celles qui n’avaient pas \u00e9t\u00e9 vaccin\u00e9es. Le risque de se faire contaminer par un membre du foyer est donc beaucoup plus \u00e9lev\u00e9 en l’absence de vaccination. Le niveau de protection, \u00e9valu\u00e9 \u00e0 14 jours apr\u00e8s la vaccination, ne variait pas selon l’\u00e2ge de la personne vaccin\u00e9e ou l’\u00e2ge des membres du foyer.<\/div>\n
En plus de prot\u00e9ger les autres, le vaccin prot\u00e8ge bien s\u00fbr avant tout la personne vaccin\u00e9e. Le Public Health England souligne aussi qu’une dose de vaccin permet \u00e9galement, apr\u00e8s quatre semaines, de r\u00e9duire de 60 \u00e0 65% le risque de d\u00e9velopper des sympt\u00f4mes pour la personne qui a re\u00e7u l’injection. \u00ab\u00a0Nous savions d\u00e9j\u00e0 que les vaccins sauvaient des vies et cette \u00e9tude, la plus compl\u00e8te men\u00e9e en conditions r\u00e9elles, montre aussi qu’ils r\u00e9duisent la transmission de ce virus mortel\u00a0\u00bb, s’est r\u00e9joui le ministre britannique de la Sant\u00e9, qui parle de \u00ab\u00a0nouvelle fantastique.\u00a0\u00bb<\/div>\n
