Lots of info on what caused the DPT scare here. There seems to be less bias in that report than in many others I read. From the report I've linked, is the following paragraph:
Until 1982 when WRC-TV in Washington, D.C. aired a documentary on pertussis vaccine reactions, most American parents (and most doctors) were unaware that the vaccine could cause death and permanent brain damage. Few parents were informed about the definition of a high-risk child or a severe reaction.
It really comes down to a sort of 'Sophie's choice':
1. Inoculate my kid, with the fairly remote chance that they'll have a significant reaction or maybe even die? Or,
2. Skip the inoculation and take the risk they'll get whooping cough... and maybe even die?
The really tough thing is to get reliable, non-biased data on the relative risks of the 2 options. What I can say for sure is that the more parents that refuse to immunize their kids, the higher the risk will become for contracting whooping cough for the general population.
Vaccination News is not against an informed parent choosing to vaccinate his or her child. Vaccination News is against bad science being used to justify forcing parents to vaccinate.
Doesn't look too unbiased to me.
