[The protective effect of hemagglutinin-specific monoclonal antibodies in experimental influenza infection]
Experiments in mice showed a high protective effect of monoclonal antibodies (MCA) to influenza A/Krasnodar/101/59 (H2N2) virus hemagglutinin, possessing neutralizing activity in ovo. A 100% protective effect was observed upon intranasal administration of MCA Kp/101-3 48 hours before infection, and 90% effect upon administration of MCA 96 hours before infection. A 100% therapeutic effect was observed upon intranasal administration of MCA Kp/101-3 less than 24 hours postinfection and 70% therapeutic effect was achieved by administration of these MCA 48-72 hours postinfection.
