About this episode

The episode discusses the development of a universal flu vaccine that could provide long-term protection against the virus.

Every year, tens of millions of people in the U.S. get the flu vaccine. That’s because the virus changes year-to-year and protection only lasts around six months. Adolfo Garcia-Sastre wants to change that. He’s one scientist working on a universal flu vaccine that could provide decades of protection against all flu illnesses – but only if his team can find the resources that disappeared when U.S. funding dipped.
