Success: More venues cancel on the American anti-vaccination campaigner.

UPDATE: 

Anti-vaccination campaigner Sherri Tenpenny, due to present seminars in Australia later this week, has had another Melbourne venue cancel her presentation after widespread community backlash. 

Melbourne’s Bay View Eden hotel called off Dr Tenpenny’s seminar after a group of doctors threatened to cancel their workshop at the venue if the anti-vaxer was allowed to present there too.

Pressure is mounting against a planned speaking tour by American anti-vaccination campaigner Sherri Tenpenny, with at least one venue now cancelling a seminar.

Dr Tenpenny, an osteopath who believes vaccines cause autism, asthma, ADHD and auto-immune disorders, is planning a series of lectures against vaccination in March aimed at parents of babies.

But she has been criticised by the Stop The Australian Anti-Vaccination Network for “endangering people’s health” and “targeting vulnerable parents”.

This woman is a danger to childre. And she’s is coming to Australia.

Kareela Golf Club in Sydney has cancelled a seminar, while a group of doctors cancelled their own workshop at a Melbourne venue, angry the place had also booked Dr Tenpenny next month.

An organiser of the tour, Stephanie Messenger, said those opposing the series of talks were trying to hide things from the public.

“They say they want parents to make an informed choice, but you can’t do that if you don’t have all the information. So they are trying to suppress the information,” she said.

A pro-vaccination group has asked Immigration Minister Peter Dutton to deny the anti-vaccination campaigner a visa to speak in Australia.

Thousands of Australians have now signed a petition lobbying Canberra to deny the visa.

Ms Messenger said cancelling the visa would set a worrying precedent.

“It would set the precedent that they can just cancel visas for anyone who hasn’t done anything wrong,” she said.

“All of Dr Tenpenny’s information is referenced by medical and scientific papers … so I don’t know what they’re trying to stop the people from seeing.”

Mr Dutton is yet to respond.

“The Minister is taking advice on this matter and will make further comment when appropriate,” a spokesman said.

Dr Tenpenny’s supporters have posted messages on Facebook, urging her to “stay strong” and that “many kids will thank her one day”.

“It’s very unfortunate that they caved into this sort of pressure, but it’s understandable … it’s unfortunate because when they do this sort of thing they allow people who want to suppress free speech to get their way.

Stop The Australian Anti-Vaccination Network member Dave Hawkes said he helped start the petition calling on Mr Dutton to deny Dr Tenpenny a visa.

“I guess the thing is you’re looking at the difference between people whose views you disagree with and people who are actually endangering people’s health,” Dr Hawkes said.
