摘要:An epidemic of cerebrospinal meningitis (CSM) in the Mongolian People's Republic, starting in 1969, reached its peak in 1974. In that year and in early 1975, 65 000 children in the 0-8-years age group in the main towns and in the provinces were immunized with meningococcal vaccine of serogroup A.
