The NSW Office of Fair Trading doorstopped the home of Australian Vaccination Network president Meryl Dorey yesterday with a letter of action, labelling the network's name misleading and a detriment to the community.

NSW Fair Trading Minister Anthony Roberts fired a broadside at the AVN, saying the information it provided was a public safety issue of "life and death".

"This is not a victimless issue, it's about the ability to stop pain and suffering," he said.

Mr Roberts likened the AVN's message to sanctioning speeding.

"People do not have the freedom of choice when it comes to endangering others ... it's the equivalent of saying a bloke can speed down the road and endanger others," he said.

Mr Roberts said he was prepared for any appeals the AVN might make.
