NOVA

Vaccines—Calling the Shots

Season 41 Episode 14 | 53m 10s

Diseases that were largely eradicated in the United States a generation ago—whooping cough, measles, mumps—are returning, in part because nervous parents are skipping their children's shots. NOVA takes viewers around the world to track epidemics, explore the science behind vaccinations, hear from parents wrestling with vaccine-related questions, and shed light on the risks of opting out.

Aired: 09/10/14 | Expires: 12/31/25 | Rating: TV-PG

Funding for NOVA is provided by David H. Koch, the Corporation for Public Broadcasting and PBS viewers. Additional funding provided by the Millicent and Eugene Bell Foundation.
