  • Publication number: 20220211837
    Abstract: The present disclosure provides compositions and methods for manufacturing and obtaining a live attenuated Influenza vaccine (LAIV) composition that can be delivered intranasally to provide protection against influenza virus infection. Said LAIV strains are based on cold adapted, temperature sensitive and attenuated phenotypes of master donor viruses (MDVs) containing the surface glycoprotein genes of the wild type pandemic or seasonal influenza strains. Also, said LAIV strains are further adapted to grow in MDCK cells (Madin Darby canine kidney cells). The use of eggs is avoided in large scale vaccine manufacturing. The purification process is devoid of chromatography steps. The said LAIV composition includes one or more live attenuated influenza vaccine virus and is devoid of polymers and surfactants.
