<p><P>PROBLEM TO BE SOLVED: To provide an effective vaccine which can elicit a wide range of desirable immune-responses to protect animals from diseases. <P>SOLUTION: The invention relates to methods and reagents for immunizing animals to elicit specific cellular and humoral immune-responses against specific antigens, such as viral antigens, including HBsAg antigen. The invention provides methods of using specifically prepared immunogen in a fresh or lyophilized liposome, proper routes of administration of the immunogen, proper doses of the immunogen, and specific combinations of heterologous immunization including DNA priming in one administration route followed by liposome-mediated protein antigen boost in a different route to tailor the immune responses in respects of enhancing cell mediated immune responses, cytokine secretion, humoral immune response, immune protection and selective skewing of T helper responses to be Th1, Th2, or a mixed or balanced Th response. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
