GUEST OVERVIEW: Dr Judy Wilyman is well placed to talk about the facts and science surrounding the current vaccine debate. She is Australia’s leading authority on the historical control of infectious diseases. She has spent many years investigating the correlation between the decline in children’s health and the increased use of vaccines. Her PhD titled ‘A critical analysis of the Australian government’s rationale for its vaccination policy’ concluded that the government’s claims of safety and efficacy are not based on hard evidence. Since completing her PhD, Dr Wilyman has experienced censorship in both the mainstream media and the official channels for public debate.
