ABSTRACT
Objective] To analyze the effect of enhanced immunization for school-age children in Hongkou District of Shanghai in immunology and epidemiology . [ Methods] One month after completing immunization, the blood antibody titers were measured by ELISA method , and compared with the those of non-enhanced immunization , for epidemiological survey were collected history of measles immunization and close contact with the measles . [ Results] It could not be thought that strengthening immunization im-proved antibody positivity rate , the protection rate , and geometric antibody average concentrations .There was not statistical difference in antibody levels between measles vaccination 2 times and 3 -4 times. [ Conclusion] In the regions where routine immunization rates reach a high level , strengthening immuni-zation done on large scale is a waste of vaccine resources , human resources and financial resources , and leak re-vaccination should be done as a cost-effective preventive measure .
ABSTRACT
[Objective] To analyse the impact factors for adult measles and its epidemiological characteristics in shanghai . [ Methods] The data on adult measles incidence during 2009-2012 were analyzed using descriptive epidemiology method .And the blood antibody titers was measured by ELISA method in the adult over18 years old in Hong Kou District of Shanghai . [Results] Zero dose vaccination and vaccination failure were the key reasons for the increase of adult measles , which were closely related to our history of prevention and treatment of measles . [ Conclusion ] Adult immunization should be strengthened to improve immune barrier and to reduce the measles incidence in adults , and it is suggested that the immunization for 10-15 year-olds should be strengthened so as to improve the overall antibody levels in adults as a whole .
