Advertising payments to news websites that publish health misinformation

JAMA Network Open

About The Study: 

From 2021 to 2024, government and health organizations accounted for about one-tenth of the $336 million in estimated advertising payments made to 11 news websites identified for publishing health misinformation. Noteworthy advertisers included federal health agencies, such as the Centers for Disease Control and Prevention, and pharmaceutical companies, such as Pfizer, although their individual contributions represented a small share of all payments.
