Immunogenic compositions comprising partially glycosylated viral glycoproteins for use as vaccines against viruses are provided. Vaccines formulated using mono-, di-, or tri-glycosylated viral surface glycoproteins and polypeptides provide potent and broad protection against viruses, even across strains. Pharmaceutical compositions comprising monoglycosylated hemagglutinin polypeptides and vaccines generated therefrom and methods of their use for prophylaxis or treatment of viral infections are disclosed. Methods and compositions are disclosed for influenza virus HA, NA and M2, RSV proteins F, G and SH, Dengue virus glycoproteins M or E, hepatitis C virus glycoprotein E1 or E2 and HIV glycoproteins gp120 and gp41.

Cette invention concerne des compositions immunogènes comprenant des glycoprotéines virales partiellement glycosylées destinées à être utilisées en tant que vaccins antiviraux. Les vaccins formulés avec des glycoprotéines de surface et des polypeptides d'origine virale mono-, di-, ou tri-glycosylés offrent une protection puissante et à spectre large contre les virus, toutes souches confondues. Des compositions pharmaceutiques comprenant des polypeptides d'hémagglutinine monoglycosylés et des vaccins générés à partir de ceux-ci ainsi que des procédés pour les utiliser en vue de prévenir ou de traiter des infections virales sont décrits. Des procédés et des compositions sont décrits pour le virus HA, NA et M2 de la grippe, les protéines RSV F, G et SH, les glycoprotéines M ou E du virus de la dengue, la glycoprotéine E1 ou E2 du virus de l'hépatite C et les glycoprotéines gp120 et gp41 du VIH.
