This is the topic of the film "Vaxxed", which was originally scheduled to be shown at the Tribeca Film Festival, but was pulled from the lineup on March 26.

The decision has created so much blowback and publicity that whoever was pushing for its removal may have cause to regret it because it has given the film a much higher public profile than if it had simply been screened as scheduled.

The Tribeca Film Festival was started by Oscar-winning actor Robert De Niro and producer Jane Rosenthal in 2001 in an effort to revitalize lower Manhattan after the 9/11 attacks.

Strange as it may seem, according to Rosenthal, it was primarily other filmmakers that were threatening to pull their films out of the prestigious festival unless "Vaxxed" was removed. De Niro says he will look into who lodged the complaints, and why.
