<p>The immune response to the weakly-immunogenic hemagglutinin subunit protein antigen (HA) of influenza virus, type A or B, and other similar weakly-immunogenic viral protein antigens, is significantly increased by covalently linking the HA to a highly immunogenic protein, such as that of a bacterial organism, for example, diphtheria toxoid and tetanus toxoid.</p> |
