Ken McLeod is a key member of the Australian Group “Stop the Australian Vaccination Network” (SAVN), which was formed in mid 2009 following the death of baby Dana McCaffery of Pertussis, a preventable illness. The group believes that the anti-vaccination propaganda issued by the AVN and its President, Meryl Dorey, is a menace to public health. Stop The AVN comprises over 2000 scientists, doctors, nurses, paramedics and laymen.
