viral neutralization

viral neutralization
the process by which antibody alone or antibody plus complement neutralizes the infectivity of a virus. The antibody may coat the virus forming a stable complex or may cause conformational changes in viral structural proteins on binding; either process may interfere with binding of the virion to cellular receptor sites and entry into the cell. Enveloped viruses may be lysed by complement.
