Polyvalent Influenza Virus-Like Particles (Vlps) And Use As Vaccines

Description

This disclosure provides compositions that include a mixture of viral like particles (VLPs), expressing different individual influenza hemagglutinin (HA) proteins that elicit broadly reactive immune responses to a wide variety of influenza viruses. For example, the composition can include at least two different influenza VLPs, a first VLP comprising a first HA polypeptide and a second VLP comprising a second influenza HA polypeptide, wherein the first and the second HA polypeptide are different subtypes and/or are from different influenza viruses, and a pharmaceutically acceptable carrier and/or an adjuvant. Methods of using the disclosed polymeric influenza VLP compositions to stimulate an immune response against influenza viruses, for example as a pre-pandemic or a seasonal vaccine, are provided.
