More than a half million deaths each year around the world result from flu-related respiratory illnesses. This year, flu has grabbed particular headlines, driven by an early start to flu season and the dominance of a particularly severe flu strain, H3N2. The flu is most dangerous to people with underlying health problems, as well as individuals over age 65 and young children. However, each year flu cases involving young, otherwise apparently healthy people raise flags. In this Forum, experts in epidemiology, immunology, and health policy will place this year’s flu season in context. They will explore vaccine development, prevention and treatment and address growing concerns globally as this particularly virulent outbreak gains the potential to spread further — ultimately asking is there a better way to stop the flu? This Forum event was presented jointly with PRI's The World & WGBH on Tuesday, February 13, 2018. Watch the entire series at ForumHSPH.org.
