The last flu season was particularly severe — causing at least 80,000 American deaths including 180 children and 900,000 hospitalizations — because of the types of influenza strains and the fact that certain groups did not get inoculated, public health officials said Thursday. They made these announcements as they kicked off their #FightFlu vaccination campaign.
Why it matters: Many of those deaths were preventable, according to U.S. Surgeon General Jerome Adams. Even when the vaccine's effectiveness is not as high as hoped, as happened last season, the shots or FluMist can still boost the immune system enough to limit how hard the virus hits as well as minimizing its spread.
