Abstract: The present invention relates to the construction of and immunization with viral vaccines. In particular, bivalent vaccines that are capable of providing simultaneous virus infection protection for two or more different viruses. Furthermore, the bivalent vaccines contemplated herein are contemplated as being effective in a neonatal mammal. One such bivalent viral vaccine comprises two antigenic epitopes against the dengue viruses and at least one antigenic epitope against hepatitis B virus. Immunization cross-reactivity may also provide infection protection against other viruses as well.

Abstract: Methods for inducing interleukin-12 production and inducing a type 1/Th1 T cell response in a subject, thereby stimulating cell-mediated immunity for prevention or treatment of pathogen infections or treatment of a interferon (-sensitive tumor, are provided. Compounds effective in the above-described methods include a lipopeptide having an N-terminal ester- or amide-linked fatty acyl group and are administered in an amount effective to induce interleukin-12 and to induce the type 1/Th1 T-cell response. Preferably, the subject is a human patient, and the lipopeptide is an N-terminal moiety of a 19 kDa or a 38 kDa lipoprotein of Mycobacterium tuberculosis.
