Abstract

Animals, including humans, are immunized by antigens, for example, the HA antigen of influenza, by first administering to a naive animal a normally strongly-immunogenic form of the antigen, for example, inactiviated or attenuated whole cell virus and subsequently administering a normally weakly-immunogenic isolated and purified viral antigen, to achieve an enhanced immune response to the purified viral antigen.
