A U.S. Army doctor has testified that she is working with Health Secretary Robert F. Kennedy Jr. and Defense Secretary Pete Hegseth to investigate whether COVID-19 vaccines caused deaths among American military personnel. The reported inquiry comes years after vaccination became a condition of continued service and thousands were discharged for refusing it. No findings definitively establishing that vaccination caused the reported deaths have so far been released. Nevertheless, the testimony brings renewed attention to a fundamental question: when governments demand compliance with a medical intervention, how fully do they accept responsibility for investigating subsequent harm and protecting the rights of those affected?
