title: [Post anthrax vaccine delayed hypersensitivity. II--delayed hypersensitivity in humans vaccinated against anthrax].
abstract: To detect cell immunity characterized by delayed postvaccination hypersensitivity to anthrax in man and assess its dynamics, vaccination using unencapsulated live anthrax vaccine was performed in 668 healthy volunteers. Vaccination was performed either by scarification (n = 172), subcutaneous injection (n = 202), or low-dose (n = 202) or high-dose (n = 83) inhalation. The anthraxin intradermal tests were performed in each patient at various times during the year following vaccination (D7, D15, D90, D180, D365). This study confirm that, regardless of the mode of administration, the vaccine induces cell-mediated immunity in man, as determined by positive anthraxine skin test. The incidence of positive tests decreases with time regardless of the mode of vaccination. After one year, the test remained positive in 34.8% of subjects vaccinated by subcutaneous injection, 37.5% vaccinated by low-dose inhalation, 34.2% vaccinated by high-dose inhalation, and 22.4% vaccinated by scarification. These findings are in agreement with those obtained in clinical epidemiological studies documenting the effectiveness of encapsulated live anthrax vaccine in man.
