Abstract:

China’s BCG strains derived from Denmark in the 1950s. Protection of different BCG strains from TB varies. The best use of BCG vaccine is to prevent life-threatening forms of tuberculosis，tuberculous meningitis and disseminated TB in infants. The adverse reactions of BCG vaccination include localized abscess，lymph node tuberculosis，osteomyelitis and disseminated BCG infection. The most common BCG accident is to mistakenly inoculate into muscles or subcutaneous tissue，and over-dose-related accidents. Appropriate and immediate treatment is urgently needed.
