Abstract
AbstractHuman influenza A/H2N2 can induce a pandemic in the future. This study evaluated the hemagglutination inhibition and neutralizing titers of intravenous immunoglobulin against A/H2N2 viruses, indicating the status of the donor population. In this study, the antibody titers decreased during the study period—2012–2021—suggesting a reduction in the immunity of the studied population.
