Scientific Review of Agent Orange in C-123 Aircraft

VA asked the Institute of Medicine (IOM) of the National Academy of Sciences, an independent non-governmental organization, to study possible exposure and increase in adverse health effects in C-123 crew members.

IOM released its report, Post-Vietnam Dioxin Exposure in Agent Orange-Contaminated C-123 Aircraft, Jan. 9, 2015. VA has assembled a group of clinical and other subject matter experts to review and respond to the report.
