The result of determining the effectiveness of measles vaccine is reported. It included 196 samples of measles vaccine from 1986 to 1989 in Xiangfang City. There were 14 samples found unqualified. Thus we took the relevant measures and the result was rather good. The investigation confirmed that the cold-chain equipment now available had played a guarantee role for the quality of vaccines. In addition, we analysed the cause of the measles vaccine with low titre. The influences of different districts and seasons on the stability of vaccine had been studied. Some measles vaccine were of low titre but rather high level in HIAb. This problem was investigated and discussed theoretically.
