Ginger Taylor is Vice President of the Canary Party, and mom to a son now much recovered from autism. Her blog, Adventures in Autism, is a thorough source of information about autism in particular, and vaccines in general. In her research into vaccines, Ginger quickly realized that the vaccine paradigm is fundamentally a political, rather than a medical, problem.
