<h1>Man Opens Fire at Federal Health Agency Over Vaccine Beliefs, Killing Officer and Injuring Others</h1> A man opened fire at a federal public health agency's headquarters, killing a responding police officer and injuring others. The shooter, armed with multiple firearms, was reportedly motivated by a belief that a COVID-19 vaccine caused him depression and suicidal thoughts. The suspect's family indicated he had become fixated on vaccine-related fears and was distressed over personal losses. The incident prompted lockdowns and security reviews at the agency, with employees expressing fear and frustration. Some former agency employees and critics attributed the violence to a climate of hostility fueled by public figures spreading vaccine misinformation and political actions undermining the agency's mission. The slain officer left behind a family, and the agency is taking steps to enhance security and address employee concerns regarding safety and misinformation.
