the seasonal flu vaccine that has not changed in recent years (volunteers were vaccinated between 2012 and 2015).
The finding is exciting «because it suggests that
the seasonal flu vaccine boosts antibody responses and may provide some measure of protection against a new pandemic strain that could emerge from the avian population,» said senior study author Paul G. Thomas, PhD, an Associate Member in the Department of Immunology at St. Jude.
Seasonal flu vaccines may protect individuals not only against the strains of flu they contain but also against many additional types, according to a study published this week in mBio ®, the online open - access journal of the American Society for Microbiology.
