A BROAD media campaign has begun to stop an American anti-vaccination campaigner running a series of lectures in Australia in March.

US anti-vaccine campaigner Sherri Tenpenny is an osteopath who is the author of Saying No to Vaccines.

She’s been invited to give a series of six seminars held in four states called ‘Healthy Lifestyles Naturally’ which has been organised by Brisbane-based anti-vaccine campaigner Stephanie Messenger.

Ms Messenger wrote the controversial children’s book Melanie’s Marvelous Measles, espousing the benefits of children falling ill with vaccine-preventable diseases.

The seminar is also supported by Ms Messenger’s Get Rid of SIDS Project.

Now debunked 40-year-old research from Japan made a tentative link with sudden infant death which has been disproved by hundreds of studies, the latest of which shows vaccinated children have a lower rate of SIDS.

The series of seminars is also being promoted on the anti-vaccination site the Australian Vaccination Skeptics Network: “Anyone who wants to learn about all aspects of natural child raising by international experts come along!”, the new president of the AVSN Tasha David said on the website.

At the seminars, Dr Tenpenny will be accompanied by another US anti-vaccine campaigner Norma Erickson, and Isaac Golden, a Melbourne-based homeopath who recommends homeopathic’ vaccines’ over regular vaccination.

Last week in the Federal Court, homeopathic vaccines were dismissed as scientifically void in an action against Homeopathy Plus which the court found falsely and misleadingly claimed homeopathic vaccines were a safe alternative.

Venues of the proposed seminars have received letters from pro-vaccine lobby groups and concerned parties.

Members of Stop the AVN, a pro-vaccine lobby group have begun a letter-writing campaign to politicians and venues hosting the seminars.

“It is extremely concerning that Tenpenny is coming here to misinform parents, she is rabidly anti-vaccine and venues might not know what their motives are. She is a public health menace,” Peter Tierney, from the SAVN, said.

People have also taken to twitter to express their concern.

How dangerous is anti-vaxer Sherri Tenpenny? This dangerous. Please write to venues & tell them #StopAVN #health pic.twitter.com/i1zjpMNb3O — Reasonable Hank (@reasonable_hank) January 4, 2015

Hey @PeterDutton_MP - use your powers to refuse a visa for Sherri Tenpenny. Way too risky to have her spreading falsehoods here in Oz. — Chris-tmas 8875 (@chris8875) January 4, 2015

Anti-vaccine campaigner Sherri Tenpenny is coming to Australia. It'd be pretty neat to get the same reaction as when Julien Blanc came here — Andy Thompson (@SweatyJester) December 30, 2014

Dr Jeremy McAnulty, Acting NSW Chief Health Officer, reminded parents that vaccine preventable diseases, such as whooping cough, measles, diphtheria, and meningitis, are serious and sometimes life threatening infections.

“There is very good evidence that the approved vaccines protect against these infection, and over the years have saved countless lives.

“Homeopathic vaccines do not provide protection against diseases such as whooping cough, measles, diphtheria, and meningitis. People who receive a homeopathic vaccine should not be lulled into a false sense of security that they or their children are protected,” Dr McAnulty said.

Health Minister Jillian Skinner said: “The best experts in the land agree that vaccination is the safest, most effective way to protect children against infectious diseases.

“There is nothing to fear from vaccination but much to fear from the devastating consequences of leaving children unprotected against potentially fatal diseases.’’
