Article: An assessment of health status among medical research volunteers who served in the Project Whitecoat program at Fort Detrick, Maryland.

ABSTRACT: Between 1954 and 1973, more than 2000 men entering military service as conscientious objectors participated in Project Whitecoat as medical research volunteers for the Army's biological warfare defense program. An assessment of self-reported, current health status among 358 "exposed" individuals and 164 unexposed control subjects found no conclusive evidence that receipt of investigational agents was related to adverse health outcomes. No differences in current overall health, current exercise levels, self-reported symptoms, and self-reported medical conditions were seen between the study groups. Possible associations were seen between exposure to antibiotics or other biological agents and self-reported asthma (13.0% vs. 2.4%, relative risk [RR] = 6.00, 95% confidence interval [CI] = 1.03-34.90, p = 0.050), as well as between receipt of tularemia vaccine(s) and self-reported asthma (13.3% vs. 2.4%, RR = 6.15, 95% CI = 1.03-36.70, p = 0.049) and increased frequency/severity of headaches (35.6% vs. 18.3%, RR = 2.46, 95% CI = 0.99-6.15, p = 0.074). However, the size of the population under study was insufficient to assert with confidence that these statistical associations are real.Military medicine 04/2005; 170(3):183-7. · 0.92 Impact Factor -
Article: Long-term health effects of repeated exposure to multiple vaccines.
[show abstract] [hide abstract]
ABSTRACT: The health of 155 former workers in a US military research program who had received multiple vaccines and 265 matched community controls was assessed. The study population was mostly male (83%) and elderly (median age, 69 years). Multiply immunized (MIP) subjects received vaccines and/or skin tests (median = 154) over a median of 17.3 years; interval from start of immunizations to survey completion was 15-55 years (mean = 43.1 years). MIP subjects characterized themselves as slightly less healthy than controls (P = 0.057). Fatigue (but no other symptom) was reported more frequently in the MIP group (P = 0.011), but was not associated with number of injections, number of vaccines, or time in program. No differences between MIP and control groups were seen for numerous self-reported medical conditions. Several statistically significant abnormalities were seen in clinical laboratory tests among MIP subjects, but none appeared to be clinically significant. A significant difference in frequency of monoclonal spikes and/or paraprotein peaks between MIP (12.5%) and control (4.5%) groups (RR = 2.7, P < 0.003) was observed; no associations with lifestyle, vaccine exposure, or medical conditions were found.Vaccine 12/2004; 23(4):525-36. · 3.77 Impact Factor
