[BCG vaccination: characteristics of drugs and causes of vaccinal complications]

Series of BCG and BCG-M vaccines causing complications in children vaccinated in Russia's areas in 1995 were checked up. All the series met the Russian and international specifications for BCG and BCG-M vaccines. The incidence of postvaccinal lymphadenitis was 5 times less than the limit laid down by an official article. The properties of the agents produced no significant effect on the number and type of postvaccinal complications. The risk for complications was much less when BCG-M was used. The risk factors were defects of intradermal vaccine administration and contaminant abnormalities prior to vaccination and at the moment of local vaccinal response.
