Peptide-Based Influenza Vaccine Formulation
Peptide-based anti-influenza formulations against influenza A and B are disclosed. The peptides are derived from influenza-based epitopes. The formulations are based on peptide mixtures which may be formulated so that variability is present at particular residues. The formulations can be used to prepare vaccines for preventing influenza in human, avian, murine or equine animals.
