LONDON — Facebook said Thursday it will start removing false claims about COVID-19 vaccines, in its latest move to counter a tide of coronavirus-related online misinformation.

In the coming weeks, the social network will begin taking down any Facebook or Instagram posts with false information about the vaccines that have been debunked by public health experts.

The U.S. tech giant is taking action as the first COVID-19 vaccines are set to be rolled out. Britain this week became the first country to give emergency authorization for a vaccine developed by American drugmaker Pfizer and Germany's BioNTech, and innoculations could start within days.
