Not a Gleek? Then tune in to UNC-TV for a very interesting Frontline episode "The Vaccine War" (9 tonight).
It's a clear-headed, one-hour look at the debate surrounding vaccine safety. That debate is between parents and activists (and parent activists) and the public health community. There are the parents who are opting out of vaccinations for fear that they are excessive and unnecessary, and the parents who believe there is a link between vaccinations and disorders like autism.
Scientists, on the other hand, say that the studies show those links don't exist and worry about the re-introduction of long dormant or preventable diseases at rates no longer seen.
