Scientists Progress Toward Universal Flu Vaccine by Targeting Hemagglutinin Protein

Researchers at Michigan State University and MIT are making strides in developing multi-year vaccines for viruses like influenza and HIV. Their work focuses on understanding how the immune system responds to different parts of the flu virus's hemagglutinin (HA) protein. Identifying whether the immune system targets the HA head or stem is crucial for creating a universal flu vaccine offering broader and more lasting protection.
