In recent years, there is a continuous outbreak of measles in Chinese universities. In order to understand the measles antibody level of college students, we take the freshmen who entered a certain university in 1988 and 1989 as the targets. According to the principle of random sampling, 89 142 The age of 16 to 20 years old, from across the country for measles antibody testing. According to the “National Plan of Immunization Management Regulations” measles hemagglutination inhibition test method. Each ear mining blood 0.3ml, serum separation, refrigeration seized. Hemagglutinin produced by Beijing biological, lot number 88-2, titer 1: 128. Monkey blood cells provided by the Henan Provincial Epidemic Prevention Station, before retesting hemagglutinin titer. Measles hemagglutination inhibition antibody ≥ 1: 2 were judged as positive. At the same time, 88 freshmen with Lanzhou biological freeze-dried measles vaccine (batch number 8802) measles vaccine re-immunization, 0.2ml per person,
