Facebook Inc on Thursday said it would remove false claims about Covid-19 vaccines that have been debunked by public health experts, following a similar announcement by Alphabet Inc’s YouTube in October, Reuters reports.

The move expands Facebook’s current rules against falsehoods and conspiracy theories about the pandemic. The social media company says it takes down coronavirus misinformation that poses a risk of “imminent” harm, while labelling and reducing distribution of other false claims that fail to reach that threshold.

Facebook said in a blog post that the global policy change came in response to news that Covid-19 vaccines will soon be rolling out around the world.
