Doctors are calling for the federal government to stop a high-profile American anti-vaccination campaigner from entering Australia for a planned speaking tour in March.

Sherri Tenpenny, a trained emergency physician and osteopath, is due to begin a series of lectures about vaccines in Melbourne on March 1. The author of Saying No to Vaccines is expected to be joined by Australian homeopath Isaac Golden, who controversially promotes the use of natural products to prevent disease.

But three months after former Immigration Minister Scott Morrison cancelled the visa of self-described "pick-up artist" Julien Blanc for allegedly spreading his derogatory views about women, Australian doctors are calling for Dr Tenpenny to receive similar treatment.

John Cunningham, a Melbourne surgeon and spokesman for pro-vaccination group Stop the AVN, said the government should not allow someone of such poor character into Australia to spread fear, paranoia and misinformation.
