Abstract
The repeat-test effect, an example of anamnestic effect in cellular immunity, was investigated in BCG-vaccinated guinea pigs, using 25 TU [tuberculin unit] Mantoux tests to influence and assess skin reactivity to tuberculin. Two different methods of quantitating the effect were tried and found valuable. The effect could be regularly observed 12 wk or more after BCG-vaccination, and with less regularity 6-9 wk after BCG-vaccination. The effect was found whether the interval between the 1st (interim) test and the 2nd (repeat) test was as short as 3 days or as long as 44 wk.
