Public health officials are voicing concern over the showing of a controversial film at an Edmonton theatre.

In a video posted to Facebook, the controversial filmmakers call on the public to support David and Collet Stephan against what they call an “incredible lying machine.”

After pulling 'Vaxxed' from the Tribeca lineup, Robert De Niro seems to defend the film and its message on the 'Today' show.

The producers of the documentary 'Vaxxed' insist it's not anti-vaccine, but its trailer is more ambiguous.
