Eurosurveillance, 2012•eurosurveillance.orgAntibody cross-reactivity to the influenza A (H3N2) variant virus recently reported in the
United States, was investigated in Norwegian sera. Seroprevalence was 40% overall, and
71% in people born between 1977 and 1993. The most susceptible age groups were
children and people aged around 50 years. The high immunity in young adults is likely to be
due to strong priming infection with similar viruses in the 1990s. More research is needed to
explain the poor immunity in 45-54 year-olds.
