YouTube will ban any video that claims vaccines are ineffective or dangerous, including those that question vaccines for measles and chickenpox, the company announced Wednesday.

"Specifically, content that falsely alleges that approved vaccines are dangerous and cause chronic health effects, claims that vaccines do not reduce transmission or contraction of disease, or contains misinformation on the substances contained in vaccines will be removed," the Google-owned company said in a blog post announcing the new enforcement measures.

The company said "vaccines in particular have been a source of fierce debate over the years, despite consistent guidance from health authorities about their effectiveness."

"Today, we're expanding our medical misinformation policies on YouTube with new guidelines on currently administered vaccines that are approved and confirmed to be safe and effective by local health authorities and the WHO."

The company said it "will continue to allow content about vaccine policies, new vaccine trials and historical vaccine successes or failures."

YouTube's COVID-19 vaccine policy has met with some backlash for being overly aggressive.

On Tuesday, the company removed Russian state-backed broadcaster RT's German-language channels, saying they violated the company's COVID-19 policy.

On Wednesday, Russia threatened to block YouTube, calling the channel removals "unprecedented information aggression."

YouTube said it has removed over 130,000 videos over the past year for violating its COVID-19 policies. (VOA/RN)
