Study provides insight on how to build a better flu vaccine

Repeated exposure to influenza viruses may undermine the effectiveness of the annual flu vaccine. A team of researchers led by Washington University School of Medicine in St. Louis has developed an approach to assess whether a vaccine activates the kind of immune cells needed for long-lasting immunity against new influenza strains. The findings could aid efforts to design an improved flu vaccine.
