The immediate effects of BCG revaccination
Although revaccination with BCG has been practised for many years, the effects of this procedure have not been studied in detail. This paper gives some results from a study of the immediate effects of revaccination, i.e., the lesion developing at the site of injection and the tuberculin sensitivity present after a few months. The data indicate that both of these responses are slightly stronger after revaccination than after first-time vaccination.The data collected in the study have confirmed that the tuberculin test has serious limitations when used for selecting candidates for revaccination.
