Y a-t-il des risques particuliers avec les vaccins bas\u00e9s sur les ad\u00e9novirus (Astra-Zeneca, Janssen) du fait de mon infection par le VIH ?<\/strong><\/span><\/h2>\n

    La r\u00e9ponse est non. Ces vecteurs viraux sont bas\u00e9s sur des virus rendus incapables de faire une infection. Le fait d\u2019avoir une infection par le VIH, ou d\u2019avoir des CD4 bas, n\u2019est pas associ\u00e9 \u00e0 un risque particulier.<\/span><\/h2>\n<\/li>\n<\/ul>\n

    Pourquoi un vaccin si rapide contre la COVID-19 alors qu\u2019il n\u2019y a toujours pas de vaccin contre le VIH ?<\/strong><\/span><\/h2>\n

      Le d\u00e9veloppement des vaccins contre la COVID-19 a b\u00e9n\u00e9fici\u00e9 des avanc\u00e9es de la recherche vaccinale des vingt derni\u00e8res ann\u00e9es, notamment en ce qui concerne le d\u00e9veloppement des vaccins \u00e0 ARNm et \u00e0 vecteur viral. Ces technologies vaccinales ont permis, d\u00e8s la d\u00e9couverte du SARS-CoV-2 et son s\u00e9quen\u00e7age complet, de lancer le d\u00e9veloppement de candidats vaccins. Comme ces technologies reposent sur le code g\u00e9n\u00e9tique du virus, elles sont tr\u00e8s rapides \u00e0 cr\u00e9er, contrairement aux anciennes approches vaccinales (culture virale, synth\u00e8se de prot\u00e9ine, etc\u2026). La mise au point d\u2019un vaccin contre le VIH est beaucoup plus compliqu\u00e9e, notamment parce que le VIH est un r\u00e9trovirus capable d\u2019int\u00e9grer son g\u00e9nome dans l\u2019ADN de ses cellules h\u00f4tes, qui sont les cellules de l\u2019immunit\u00e9. Il \u00e9chappe ainsi \u00e0 la vigilance du syst\u00e8me immunitaire. De plus, il existe une multitude de virus VIH qui diff\u00e8rent entre eux, bien plus que pour le SARS-CoV-2.<\/span><\/h2>\n<\/li>\n

        Le vaccin est-il plus ou moins efficace chez moi ? Est-il efficace si mes CD4 sont bas ?<\/strong><\/span><\/h2>\n<\/li>\n<\/ol>\n

          Il n\u2019y a pas de donn\u00e9es pour penser que les Personnes vivant avec le Vih ( PVVIH ) auraient en g\u00e9n\u00e9ral une moins bonne r\u00e9ponse au vaccin. \u2022\u00a0 il n\u2019y a\u00a0 aucune raison de penser que les vaccins soient moins efficaces chez les PVVIH avec un taux de CD4 normal. Pour ceux qui sont plus immunod\u00e9prim\u00e9s, il est possible que la r\u00e9ponse immunitaire soit moins bonne, comme pour tous les vaccins. Cependant, la forte immunog\u00e9nicit\u00e9 (capacit\u00e9 \u00e0 d\u00e9clencher une r\u00e9ponse immunitaire) des vaccins ARNm permettra probablement de g\u00e9n\u00e9rer une bonne r\u00e9ponse immunitaire, m\u00eame chez ces personnes immunod\u00e9prim\u00e9es \u00e0 cause d\u2019un taux tr\u00e8s bas de CD4.<\/span><\/h2>\n<\/li>\n
