[Report of clinical testing of BCG vaccine (Strain "1331 Copenhagen") for vaccination of newborns against tuberculosis (author's transl)].

BCG vaccination with the vaccine "1331 Copenhagen" in various concentrations was carried out in 129 newborns. Control examinations were conducted to establish the complication rate and the percentage of tuberculin-positive children. Complications, either locally or in regional lymphatic areas, did not appear. The conversion rate increased with the number of viable units pro dose of vaccine. A vaccine with a concentration of about 250,000 units of vaccine pro dose is recommended for additional clinical testing.
