A CONTROVERSIAL Australian pressure group that claims vaccines can cause brain damage and cancer says it has been the victim of a witch-hunt after it was stopped from spreading its message overseas.
Australian Vaccination Network, which has been criticised for putting out misleading and irresponsible information based on "conspiracy theories", had planned to run ads on American Airlines' in-flight TV channel.

But just one month after the ads were announced, AA pulled the plug on the ads, which would have aired in June and July and which AVN claims would have been seen by 8.4 million people .
