Plot Summary:From PBS and NOVA - Diseases that were largely eradicated in the United States a generation ago--including whooping cough, measles, mumps--are returning, in part because nervous parents are skipping their children's shots. Vaccines - Calling the Shots, a new NOVA special, takes viewers around the world to track epidemics, explore the science behind vaccinations, and shed light on the risks of opting out. The vast majority of Americans vaccinate their children, and most do it on the recommended schedule. Yet many people have questions about the safety of vaccines, and in some communities, vaccination rates have fallen below the level needed to maintain "herd immunity" --allowing outbreaks to take hold and spread. This film draws on the latest, best available evidence to help parents find the answers. Highlighting real cases and placing them in historical context, Vaccines--Calling the Shots traces outbreaks of communicable diseases and demonstrates just how fast they can spread--and how many people can fall sick--when a community's immunity barrier falls.
这篇的介绍重点在于呼吁人们接种疫苗，列举了一些（许多被推翻的和一个被确认的）疫苗导致的疾病。制作组很用心，但由于堆叠正面论据太多，语气太强硬，我认为对于那些本身就对疫苗持反对态度的人来说，大概率是没有什么说服力的，甚至可能会被称作“伪纪录片”。对于要起呼吁性作用的纪录片来说，这个已经属于硬伤了。
