Gunfire aimed at the U.S. Centers for Disease Control and Prevention by a man authorities say was angry over COVID-19 vaccines is the latest in a string of violence and harassment directed at health care workers amid hostility lingering from the pandemic.

The suspected gunman who attacked the Centers for Disease Control and Prevention's campus on Friday may have fired many hundred rounds, law enforcement said on Tuesday.

The CDC director described the dangers of misinformation, four days after a gunman shot at the headquarters in Atlanta, claiming the COVID-19 shot sickened him.
