What Was Operation Whitecoat?

What Was Operation Whitecoat

In 1954 at Fort Detrick, the Army conducted a top secret experiment called Operation Whitecoat to test volunteers with various infections such as Q fever, tularemia, yellow fever and Venezuelan equine encephalitis.

Over 2,300 noncombatant conscientious objectors from the Seventh Day Adventist church volunteered for these experiments and were exposed to infectious pathogens as well as tested with experimental vaccines.

It was a Cold War experiment

Many conscientious objectors who participated in this program were members of the Seventh Day Adventist Church. These volunteers volunteered for experiments involving viruses, bacteria and parasites which could potentially be used against US troops or civilians; doing this under cover of Cold War at a time when few scrutinized government practices was rarely done so without oversight by anyone in society.

Between 1954 and 1973, the Army enlisted over 2,300 men in Operation Whitecoat at Fort Detrick in Maryland as participants called “Whitecoats.” These soldiers participated in medical experiments designed to develop vaccines against deadly pathogens that might be used as biological warfare weapons.

Researchers exposed some subjects to pathogens like Q fever, tularemia, yellow fever and plague – diseases with no proven cure at the time. Some men were quarantined for weeks in cramped living conditions where three meals a day and television were their sole amenities.

Research participants were informed that their participation would help defend US troops and civilians against biological weapons, in accordance with the Nuremberg Code – which establishes ten principles for human experimentation – as well as being compliant with the Nuremberg Code’s principles for experimentation on humans. Colonel William D Tigertt, Army commander at that time, also consulted leaders of Seventh Day Adventist Church leaders to ensure this project aligned with their church’s mission statement.

It was a test

During the Cold War, over 2,300 noncombattant conscientious objectors from Seventh-day Adventist churches volunteered for Army medical experiments that involved developing defensive medical countermeasures against Soviet biological warfare capabilities. Volunteers were exposed to experimental vaccines and infectious pathogens. Operation Whitecoat chronicles their heroic journey; one which celebrates both patriotism and courage.

Researchers started out by giving some participants low doses of pathogens; if they did not become sick, higher doses would be administered in subsequent rounds until approximately 80 percent of subjects became ill – using this information to create vaccines against diseases like Q fever, tularemia, yellow fever, encephalitis and plague.

Many subjects volunteered for these studies despite knowing they would serve as human test subjects, believing they were helping their country and even risking their lives to protect family and others who could potentially be exposed to biological attack.

These hardworking people and women helped to develop 13 vaccines still used today, such as yellow fever, hepatitis A, tularemia (rabbit fever), Venezuelan equine encephalitis and Rift Valley fever vaccines. Cholera, Hepatitis B and Plague vaccines are also currently under development – many are already being deployed worldwide to contain large epidemics.

It was a guinea pig experiment

In 1954, the US Army initiated medical research at Fort Detrick in Maryland on enlisted soldiers known as White Coats during the Cold War – this top secret research was intended to protect troops and civilians against biological weapons. Before agreeing to take part, volunteers mostly from Seventh-Day Adventist churches were informed about its purpose and goals before participating.

White Coats were subjected to various tests, including exposure to pathogens like Q fever, tularemia and yellow fever; blood tests and electrocardiograms; three meals daily plus television viewing and ping pong playing – though most participants did not fall ill during this research experiment despite its risks; nonetheless it sparked much controversy and debate.

While their experiment did not result in vaccines, scientists learned much from it about how pathogens impact humans. Notably, they discovered it is possible for pathogens to make people sick without direct contact, and discovered they spread quickly over long distances.

During the Cold War, many were concerned that microbiology was rapidly moving towards creating biological weapons. Koch had accomplished much in terms of naming organisms but had done little to protect humans’ lives.

It was a human experiment

In 1954, the Army initiated a series of medical experiments on volunteer enlisted personnel without weapons – many belonging to Seventh-day Adventist churches – intended to defend troops and civilians against biological warfare. At Fort Detrick researchers were aware of their responsibility under the 1947 Nuremberg Code for informed consent of human subjects as part of this research program.

Enlisted soldiers were briefed both individually and as a group, giving them an opportunity to pose any queries and sign a consent form before participating in any project. Volunteers were offered the chance to opt out at any point; although some did choose to continue for the entirety of the program.

Ken Jones spent six months volunteering at the base, being subjected to X-rays, blood tests and electrocardiograms as well as being exposed to bacteria and viruses including Rift Valley fever, Hepatitis A infection, Yellow fever infection and Yersinia pestis (plague).

Whitecoat participants generally did not become sick due to their participation, although some did become ill due to antibiotic treatment; these volunteers eventually recovered with no lasting health problems and many even married after participating. A soldier participating in a vaccine study for western equine encephalomyelitis – an inflammation of the brain and spinal cord – managed to hold down a job as a newspaper printer in Washington while playing softball for Fort Detrick softball team and attending his weekly church services.


In conclusion, Operation Whitecoat stands as a distinctive and complex chapter in the history of military-medical collaboration during the Cold War era. Born out of a unique intersection of scientific research, conscientious objection, and military objectives, this biomedical program involved volunteers, predominantly from the Seventh-day Adventist Church, who willingly participated in experiments studying the effects of biological warfare agents.

The legacy of Operation Whitecoat extends beyond the scientific contributions and military initiatives. It highlights the human aspect of conscientious objectors who, motivated by their beliefs and commitment to nonviolence, played a crucial role in advancing medical knowledge. The program’s impact on conscientious objection policies within the U.S. military and its ongoing relevance in contemporary discussions on ethics and scientific research further underscore its significance.
