Analysis of the examination findings from of 80 children who had postvaccination lymphadenitis in their early childhood was made. The observation period covered 8-10 years. Regional lymphadenitis in the infiltration stage was detected in 23 (28.8% of the children); in the abscess formation stage in 42 (52.5%); and in the calcification stage in 15 (18.7%). The children were treated with antibacterial drugs for 2-4 months, thus producing positive results. However, 1 or 2 years after recovery there were 5 recurrent cases. During 8-10 years which followed BCG vaccination none of the 80 children had tuberculosis. The study proves the fact the cured postvaccination lymphadenitis does not affect the formation of antituberculous immunity.
