[Comparative immediate results after the use of several lyophilized BCG vaccines].

A number of 1928 children were vaccinated intradermally with 12 series of BCG vaccine produced by the Cantacuzino Institute and 2 experimental vaccines, prepared in the same laboratory by the same current technique, i.e. a Romanian strain and a French strain, lot 1173 P2. With the experimental vaccines 2 doses were used, with the other vaccines a single standard dose of 0.10 mg. Appraisal of tuberculin sensitivity 8-10 weeks after vaccination showed differences in tuberculin duration, varying between 13.23 mm and 16.27 mm in diameter with the selected vaccines (using 2 units PPD) and were much smaller (8.6 mm -- 12.28 mm) with the operational series of vaccines.
