Pagination or Media Count:
To evaluate the potential for long-term or delayed onset health effects, we extended a previous cohort study of disability separation from the army associated with vaccination against anthrax. Analyses included stratified Cox proportional hazards and multiple logistic regression models. Forty-one percent of 1,001,546 soldiers received at least one anthrax vaccination 5.21 were evaluated for disability. No consistent patterns or statistically significant differences in risk of disability evaluation, disability determination or reason for disability were associated with anthrax vaccination. There was a dose-related trend in risk of disability for soldiers with 2 years service, limited to those entering service in 2000 or later. Divergent patterns in risk suggest confounding by temporal or occupational risks of disability.
