H3N2 viruses mutate during vaccine production but new tech could fix it

(University of Wisconsin-Madison) A new technology developed by the University of Wisconsin-Madison's Yoshihiro Kawaoka may make H3N2 vaccine development a bit easier. In Nature Microbiology today [April 29, 2019], Kawaoka and his team describe a new cell line that enables better growth of H3N2 for vaccine use. The virus is also far less likely to mutate during production using this cell line, improving the chances of a match between vaccine and circulating influenza viruses.
