Vietnam Era Recruits Exposed to Experimental Vaccinations

With a predilection for jet injector technology, the Department of Defense (DoD) used jet infector devices to administer many common immunizations as well as many experimental vaccines. Military recruits throughout the 1960s and 1970s were often used to test experimental vaccines, often without any informed consent to the injections or possible side-effects they were about to receive. Here are several known examples of experimental vaccinations given by jet injections upon Vietnam era recruits:

In 1970, young servicemen at five Army Basic Training Facilities were used to test the first modern polysaccharide vaccine. Artenstein and colleagues gave an experimental Group C polysaccharide vaccine to 13,763 Army recruits in the hopes of preventing meningococcal disease. Three facilities administered the vaccine with Ped-O-Jet injectors: Fort Dix (4,133 recruits), Fort Polk (2,830 recruits), and Fort Bragg (2,290 recruits). Thankfully, the results showed Group C polysaccharide vaccine was safe and effective (Artenstein et al., 1970).

Navy recruits stationed at Great Lakes Naval Training Center were used to compare the administration of typhoid vaccinations by jet injection to syringe. “The use of an automatic jet injection apparatus would make mass immunization against typhoid quicker and less costly,” said the researchers. Edwards and colleagues (1974) administered a monovalent acetone-inactivated dried typhoid vaccine (AKD) and a heat-killed polyvalent typhoid-paratyphoid aqueous vaccine (TAB) to 306 volunteer recruits, aged 19 to 25 years. Local reactions, such as pain, erythema, and tenderness were noted in the recruits. Reactions were more prevalent when administered via Ped-O-Jet injectors than by syringe. “Eighty-eight and 82%, respectively, of AKD- and TAB-treated men showed one or more local reactions 24 hours following jet injection, whereas only 24% of those who received vaccine by syringe” (Edwards et al., 1974). In 1990, the CDC reported as a result of Edwards’ study that “Administration of the acetone-inactivated vaccine by jet-injector gun results in a greater incidence of local reactions and is not recommended.” The report also noted that TAB vaccines were not effective and increased the risk of vaccine reaction (CDC, 1990).

Benenson and Phillips (1976) studied the administration of smallpox vaccination by intradermal jet injection when this method was found unconventional five years prior. From October 1973 to June 1974 the researchers studied 10,257 Army recruits at Fort Knox, Kentucky receiving smallpox vaccination by jet injection. This method was associated with more recruits visiting “sick call” and unable to perform military duties. Although during this time frame, the non-military medical profession had long abstained from using jet injectors for smallpox vaccinations, instead using the simpler, cheaper bifurcated needle. Dr. Bruce Weniger, formerly of the CDC, wrote:

Bifurcated needles were developed and introduced midway through the World Health Organization’s 1959-1977 campaign to eradicate smallpox, and by 1969 completely replaced jet injectors which had been used during the early years of the effort. Bifurcated needles are highly preferable for conducting mass vaccination with existing (and ordered) stocks of smallpox vaccine than would be the use of any existing high-speed jet injector, on grounds of speed, simplicity, training, frugality, flexibility, and safety (Weniger, 2002).

Lastly Benenson and Phillips noted the numerous vaccinations recruits received upon entering bootcamp.

Recruits reporting to Ft. Knox are given basic immunization with tetanus-diptheria toxoids and poliomyelitis, meningitis, and monovalent influenza vaccines. 8 to 14 days later they received a dose of typhoid vaccine and smallpox vaccine by jet injection. A week later the smallpox vaccinations were read, and a dose of bivalent influenza vaccine administered. It was decided to utilize this routine immunization program, to define the morbidity resulting from primary vaccinations (Benenson & Phillips, 1976).

 

The use of military personnel as subjects in experimental studies exposed these men and women to not only more jet vaccinations than the public but also increased their risks to the ill affects of the vaccines, frequent local reactions at the injection site, and exposure blood and blood-borne pathogens.
