Ken McLeod is a key member of the pro-vaccination Group “SAVN'”. The group 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 (Australian Vaccination Network) and its President, Meryl Dorey, is a menace to public health. “Stop The AVN” comprises over 2,000 scientists, doctors, nurses, paramedics and laymen.
