Broader vaccine protection against flu and COVID-19,

Researchers at UW–Madison have provided new insights into an alternative vaccine approach that provides broader protection against seasonal influenza as well as other respiratory pathogens, including COVID-19. The experimental vaccine delivered long-lasting, multi-pronged protection in the lungs of mice by rallying T-cells, specialist white blood cells that quickly eliminate viral invaders through an immune response. The research suggests a potential strategy for developing a universal flu vaccine so a new vaccine does not have to be developed every year.
