"The Vaccine War" - Preview
FRONTLINE investigates the science and the politics of vaccine safety. Amid a new outbreak of measles, health officials are once again urging parents to immunize their children and reassuring them that there is no link between vaccines and disorders like autism. But the war over vaccines rages on. An updated version of FRONTLINE's 2010 film "The Vaccine War" airs Mar. 24 on PBS and online.
