Polyvalent Influenza Virus-Like Particles (VLPs) and Use as Vaccines
Influenza virus is a major public health concern, causing up to 500,000 deaths annually. The current strategy of reformulating vaccines annually against dominant circulating strains leads to variable protective efficacy and is unlikely to protect against novel influenza viruses with pandemic potential. Thus, there is a great need for a vaccine that provides “universal” protection against influenza viruses.
