On Friday, YouTube said it would ban channels that promote content that advocates vaccination from running advertising.
A company spokesperson told BuzzFeed News in a statement that such content is in violation of the policy that prohibits revenue generation of videos containing "dangerous and harmful" material.
"We have strict guidelines that govern which videos we allow ads to appear on, and videos that promote anti-vaccination content violate these guidelines," the representative said.
"We strongly enforce these guidelines, and if we find a video that violates them, we immediately take action and remove ads," they added.
According to Buzzfeed, the move comes after a number of advertisers withdraw their ads such videos in the last few days. [1
The ads also show up on content published under other channels as an advocate against vaccination, including VAXXED TV and iHealthTube, Buzzfeed reported. These channels have since been demonized by YouTube or prevented from running advertisements, according to the withdrawal. A health care professional, Nomad Health, told Buzzfeed that it was not "aware that our ads are running alongside anti-vaccination videos" and "does not support the anti-vaccination movement, adding that it would" take action to prevent it from happening in the future.

A spokesman for Vitacost, a vitamin company who also allegedly had similar content ads, told the publication that it "pulled all YouTube advertising Tuesday morning when we noticed content issues."
"We had strict rules to prevent our ads from serving sensitive content, and they were not effective as promised," said the spokesman.
"We will continue to stay out of the platform until those changes are made and proven to be effective by other advertisers," they added.
