Patent number: 10849943Abstract: The present invention relates to vaccine compositions comprising an attenuated mutant Zika virus. The inventors have introduced mutations at very specific positions that abrogate the N-glycosylation site on the E protein of the epidemic strain which will prevent the generation of auto-antibodies responsible for Guillain-Barre syndrome. The inventors have also produced additional mutations of the virus that result to a dramatic reduction of the cytopathic effects without affecting the capacity to produce high titers of virus. In particular, the present invention relates to an attenuated mutant Zika virus comprising a protein E of the epidemic strain wherein at least one amino acid residue at position 152, 156 or 158 is mutated.Type: GrantFiled: June 22, 2017Date of Patent: December 1, 2020Assignees: INSERM (INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE), UNIVERSITE DE LA REUNION SAINT DENIS, INSTITUT DE RECHERCHE POUR LE DEVELOPPEMENT (IRD), CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE-CNRSInventors: Philippe Despres, Gilles Gadea, Patrick Mavingui, Wildriss Viranaicken
