Serologic conclusions Studies with human sera collected after immunization with current vaccines show that: • H1N1 • Representative recent viruses were less well inhibited by HA antibodies to current vaccine strains (A/Solomon Islands/3/2006-like virus). • H3N2 • Representative recent viruses were less well inhibited by HA antibodies to current vaccine strain (A/Wisconsin/67/2005-like virus). • B • B/VICTORIA/2/87-lineage • Representative recent viruses were well inhibited by HA antibodies to current vaccine strain (B/Malaysia/2506/2004-like virus). • B/YAMAGATA/16/88-lineage • Representative recent viruses generally were less well inhibited by HA antibodies to the current vaccine strain. 20
