Abstract excerpt
BACKGROUND: The direct effect of antigenic site mutations in influenza viruses on antigenic drift and vaccine effectiveness is poorly understood. OBJECTIVE: To investigate the genetic and antigenic characteristics of human influenza A (H3N2) viruses circulating in Ontario during the early 2010-2011 winter season. STUDY DESIGN: We sequenced the hemagglutinin (HA) and neuraminidase (NA) genes from 41 A(H3N2)...
