Abstract

The invention relates to composite antigens comprising a peptide with contiguous amino acid sequence derived from a plurality of antigenic epitopes of one or more pathogens that induces an immune response in a mammal that is protective against infection by the one or more pathogens. In addition. The invention also relates to antibodies to composite antigens of the invention and to methods of administering vaccines comprising antigens or vaccines of antibodies for treating and/or preventing an infection.
