WASHINGTON (AP) — President Joe Biden says social media companies are “killing people” by failing to police misinformation on their platforms about the COVID-19 vaccines. Biden’s comment on Friday came a day after U.S. Surgeon General Vivek Murthy declared misinformation about the vaccines a threat to public health. The president, asked if he had a message for platforms like Facebook where false or misleading information about the coronavirus vaccines is spreading , told reporters, “They’re killing people.” U.S. officials advise that deaths and serious illness from the virus are nearly entirely preventable because of the vaccines.
