Lies and conspiracy theories about Covid-19, which have amassed millions of views and are accessible to young children, have remained on the social media platform TikTok for weeks after it was alerted to them, the Guardian has learned.
TikTok accounts with hundreds of thousands of followers that discourage vaccination and peddle myths about Covid survival rates were uncovered by NewsGuard, an organisation that monitors online misinformation.
Newsguard said it published its findings in June and sent them to the UK Government and WHO. They raised concerns about some of the content directly with TikTok last month, but it remained on the platform.
The revelation comes amid renewed concern about the impact that social media is having on young people, after it was reported that Instagram, which is owned by Facebook, had internal research showing its app was harming teenagers.
