2009 H1N1 pandemic influenza (A(H1N1)pdm09) virus infected large numbers of people worldwide. Recent studies suggest infection with A(H1N1)pdm09 virus elicited cross-reactive anti-hemagglutinin (HA) memory B cell response to conserved regions of HA. However, the breadth and magnitude of cross-reactive immunity in children and adults following A(H1N1)pdm09 infection are unknown. ⋯ Our results suggest individuals exposed to A(H1N1)pdm09 virus developed a broad and age-associated cross-reactive anti-HA immunity which may have important implications for future vaccination strategies to enable protection against a broader range of influenza viruses.
