Effect of number of BCG vaccination on tuberculin induration size.

AIM The aim of this study is to interpret purified protein derivative (PPD) induration sizes with respect to the number of Bacillus Calmette-Guérin (BCG) scars. METHODS We have considered 1879 school children between the ages of 7 and 14 years from seven primary schools in Kocaeli, Turkey. Children were injected with 5TU 0.1 mL PPD and induration sizes were measured at 72 h. Number of BCG sca...
