Facebook founder Mark Zuckerberg said the social media company will label what it determines is "credible information" about COVID-19 vaccinations.
The company will add labels to posts about the vaccines, which will contain "credible information" from the World Health Organization (WHO), Zuckerberg said in a blog post. WHO has been widely criticized for its response to the pandemic.
"We're adding a label on posts that discuss the safety of COVID-19 vaccines that notes COVID-19 vaccines go through tests for safety and effectiveness before they're approved," Zuckerberg said.
Facebook has been criticized by some for failing to act against what some call misinformation about the vaccines.
The company said it was also going to supply users with information on how to get vaccinated.
