Recognition of influenza H3N2 variant virus by human neutralizing antibodies. JCI insight. 2016 Jul 7;1(10). PMID: 27482543 [PubMed]. PMCID: PMC4962875. NIHMSID: NIHMS801311.
Since 2011, over 300 human cases of infection, especially in exposed children, with the influenza A H3N2 variant (H3N2v) virus that circulates in swine in the US have been reported. The structural and genetic basis for the lack of protection against H3N2v induced by vaccines containing seasonal H3N2 antigens is poorly understood. We isolated 17 human monoclonal antibodies (mAbs) that neutralized H3N2v virus from subjects experimentally immunized with an H3N2v candidate vaccine. Six mAbs exhibited very potent neutralizing activity (IC50
