YouTube will remove videos spreading misinformation on its platform about any approved vaccine, not only those aimed at preventing Covid-19.

Users who post misinformation about any “currently administered vaccines that are approved and confirmed to be safe and effective by local health authorities and the WHO” will be subject to YouTube’s strike policy and could face removal, the company said in a blog post.
