Facebook to remove false claims on vaccines

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. Regulators in the U.S., the European Union and Canada are also vetting vaccines.

Facebook said it’s applying a policy to remove virus misinformation that could lead to “imminent physical harm.”

Posts that fall afoul of the policy could include phony claims about vaccine safety, efficacy, ingredients or side effects.

“For example, we will remove false claims that COVID-19 vaccines contain microchips, or anything else that isn’t on the official vaccine ingredient list,” the company said in a blog post.

Conspiracy theories about the vaccines that are already known to be false will also be removed.

Facebook has taken other steps to try to stop the spread of vaccine and coronavirus-related misinformation on its platform. From March to October, it has removed 12 million posts with coronavirus-related misinformation. The deleted posts include one by President Donald Trump with a link to a Fox News video of him saying children are “virtually immune” to the virus.

In October, the company banned ads discouraging vaccinations, though it made an exception for advocacy ads about government vaccine policies. The company has also promoted articles debunking COVID-19 misinformation on an information center.
