FCGR2A and infection: Whilst the combined logistic regression model had non-significant results for FcR contributions, results from the V0S0 group throughout point to the importance of elevated pH1N1-reactive IgG1, FcγR2a, and FcγR3a in this group as protective from pH1N1 infection that may extend to other avian H5 viruses based on antibody correlation networks.
