Social media giant Facebook, for the first time, has removed a post from US President Donald Trump in which he claimed that children were "almost immune" to COVID-19, saying it violated its policy against spreading "misinformation" about the novel coronavirus.

Axar.az reports citing foreign media that the post in question was a video clip of a Trump interview on Fox News Channel uploaded by the Trump campaign on Wednesday. The US President claims in the clip that children are "almost immune" to COVID-19.

While much remains unknown about the novel coronavirus, children can contract COVID-19 and are believed to be able to spread it to others, even without symptoms. "This video includes false claims that a group of people is immune from COVID-19 which is a violation of our policies around harmful COVID misinformation," Andy Stone, a Facebook policy spokesperson said in a statement.

A link to the post now diverts to a page that says, "This Content Isn't Available Right Now." It is the first time that Facebook has removed a post from Trump entirely, rather than labelling it, as it has done in the past, making it a rare instance in which it has been willing to censor the president.
