TikTok is stamping down on vaccine misinformation, introducing a new content screen for videos that might be harmful, and clarifying its rules worldwide.
The announcements came on the same day when the UK government warned of a "new age of accountability" for social media.
Social-media platforms operating in the UK could be fined 10% of global turnover for not following the rules.
"It is more important than ever to ensure that misinformation that could harm wider public safety is not allowed to proliferate online," Kevin Morgan of TikTok said.
TikTok has announced a suite of changes meant to tackle vaccine misinformation, clarify rules about the app, and protect users from questionable content.
