Universal flu vaccine identified

Potential vaccine for flu

  • Scientists have identified a potential universal influenza vaccine that could protect people against most strains of the virus
  • The candidate vaccine elicited a strong antibody response to a structure on the surface of flu viruses, called the hemagglutinin (HA) stalk
  • It has the potential to be developed into a universal flu vaccine, which — unlike the current seasonal flu vaccines — could be given a few times over a lifetime to provide protection potentially similar to a tetanus vaccine

Current usage of vaccines

  • Modern viral vaccines typically use lab-grown viral proteins to elicit an immune response that protects people against future exposures to a virus
  • Seasonal flu vaccines provide temporary protection against the flu
