A U.S. military official predicted a pause in the administration of the Moderna and Pfizer COVID-19 vaccines could happen if more cases of post-vaccination heart inflammation were detected, according to newly obtained emails.
Harry Chang, a U.S. Army lieutenant colonel, made the prediction on April 27, 2021—the same day the director of the U.S. Centers for Disease Control and Prevention (CDC) said the agency was not seeing a safety signal when it came to heart inflammation experienced after getting a COVID-19 vaccine.
