All year long, researchers at hospitals around the world collect samples from flu patients and send them to top virology experts with one goal: to design the vaccine for the next flu season. But why do we need a new one every year? Vaccines for diseases like mumps and rubella offer a lifetime of protection with two shots early in life; what’s so special about the flu? Melvin Sanicas explains. [Directed by Andrew Foerster, narrated by Addison Anderson, music by Devin Polaski].

After the talk, Shoshana interviews Dr. Michael Osterholm, an epidemiologist, to discuss the issues surrounding global public health and why science matters.  For more of Dr. Michael Osterholm, check out his podcast Osterholm Update.
