American singer Selena Gomez called out Facebook for "spreading lies" about the COVID-19 vaccine. 

The singer fired off a pointed tweet on Tuesday (Dec. 29) decrying what she said was the social media giant's failure to stop the spread of misinformation about the life-saving COVID-19 vaccines that are rolling out across the country and the world.

She wrote on twitter that "Scientific disinformation has and will cost lives. @Facebook said they don’t allow lies about COVID and vaccines to be spread on their platforms. So how come all of this is still happening? Facebook is going to be responsible for thousands of deaths if they don’t take action now".

Her tweet included a link to a post from the Center for Countering Digital Hate in which the group's CEO, Imran Ahmed, spoke to the BBC News about what he said was the critical, widespread failure of major social media companies to remove coronavirus misinformation in the UK.

In the video, Imi Ahmed said that social media platforms have done nothing to stop the spread of false information about the vaccine and the pandemic. He also cited experiments that his non-profit organisation has conducted to reach that conclusion.
