In the 1960s, close to 5,900 military personnel, mostly Navy and Marines, participated in Project SHAD—a series of classified tests of U.S. warship vulnerability to biological and chemical warfare agents. Many of the tests used simulants, substances with the physical properties of chemical or biological warfare agents but considered at the time to be harmless. The existence of these tests became public many decades later. Only some of the involved military personnel were aware of the nature of the tests at the time they were conducted.

Veterans who participated in the Project SHAD (Shipboard Hazard and Defense) tests showed no significant increase in adverse health outcomes, specific causes of death, or death rates compared with a similar group of veterans who were not involved in the tests, says a the new report from a committee of the National Academies of Sciences, Engineering, and Medicine. The congressionally mandated report builds on a 2007 Institute of Medicine report, which also found no consistent, specific patterns of poorer health among SHAD veterans - See more at:
