Serologic ConclusionsStudies with human sera collected after immunization

with current vaccines show that:• H1N1

– Representative recent viruses were modestly inhibited by HA antibodies to current vaccine strains (A/Brisbane/59/2007-like virus).

• H3N2– Representative recent viruses were well inhibited by HA

antibodies to current vaccine strain (A/Brisbane/10/2007-like virus).

• B– B/VICTORIA/2/87-lineage

• Representative recent viruses were not well inhibited by HA antibodies to current vaccine strain (B/Florida/4/2006-like virus).

– B/YAMAGATA/16/88-lineage• Representative recent viruses were well inhibited by HA antibodies to the current vaccine strain.
