Next generation methodology for updating HA vaccines against emerging human seasonal influenza A(H3N2) viruses

open access: yesScientific Reports, 2021
While vaccines remain the best tool for preventing influenza virus infections, they have demonstrated low to moderate effectiveness in recent years. Seasonal influenza vaccines typically consist of wild-type influenza A and B viruses that are limited in ...

Opposing Effects of Prior Infection versus Prior Vaccination on Vaccine Immunogenicity against Influenza A(H3N2) Viruses

open access: yesViruses, 2022
Prior vaccination can alternately enhance or attenuate influenza vaccine immunogenicity and effectiveness. Analogously, we found that vaccine immunogenicity was enhanced by prior A(H3N2) virus infection among participants of the Ha Nam Cohort, Viet Nam ...

Egg-adaptive mutations of human influenza H3N2 virus are contingent on natural evolution

open access: yesPLoS Pathogens, 2022
Egg-adaptive mutations in influenza hemagglutinin (HA) often emerge during the production of egg-based seasonal influenza vaccines, which contribute to the largest share in the global influenza vaccine market.

N-Linked Glycosylation Attenuates H3N2 Influenza Viruses [PDF]

open access: yesJournal of Virology, 2007
ABSTRACT Over the last four decades, H3N2 subtype influenza A viruses have gradually acquired additional potential sites for glycosylation within the globular head of the hemagglutinin (HA) protein. Here, we have examined the biological effect of additional glycosylation on the virulence of H3N2 influenza viruses. We created otherwise
