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.

The campaign will feature the slogan Let's Not Go Back and will show group activities and events - such as concerts - that will be possible again after the pandemic.
