A seroconverted subject was defined as a vaccinated subject who had either a pre-vaccination titer \< 1:10 and a post-vaccination titer ≥1:40, or a pre-vaccination titer ≥1:10 and at least a four-fold increase in post-vaccination titer. The 4 influenza strains assessed were the FLU A/California/7/09 (H1N1), FLU A/Victoria/210/09 (H3N2), FLU B/Brisbane/60/08 (Victoria) and FLU B/Brisbane/3/07 (Yamagata).
