YouTube has launched a multi-million-pound advertising campaign to encourage young people in the UK to get vaccinated against Covid-19.
It said the partnership with the NHS would involve ads on buses, billboards, bus stops and YouTube, with the video-sharing site paying for them.
YouTube has been criticised for being slow to stop the spread of coronavirus disinformation.
But it said it had removed 900,000 Covid-19 videos that broke its rules.
