OBJECTIVE: To understand the level of measles antibody in healthy population in Sinan County, assess the effect of vaccination and the population immunization status, and provide the basis for formulating immunization planning strategies and prevention and treatment measures. Methods: A total of 313 healthy subjects were selected according to the principle of random sampling. ELISA was used to detect the measles IgG antibodies. Results: A total of 313 serum samples were tested. The total positive rate of measles IgG was 74.44%. The positive rate of measles IgG was also significantly different among all age groups. The positive rate of 8 - 12 months was very low. Conclusion: The first work of measles vaccine should be strengthened to strengthen the management and vaccination of immunization blankets and floating population children. The leak detection and replanting of measles vaccine should be carried out in a planned way to strengthen the management of cold chain and improve the effective vaccination rate of measles vaccine.
