  • Testing and Analysis of Antigen and Antibody for Children's Immunization Program Targeted Diseases

    ObjectiveTo summarize the results of testing and analysis of antigen and antibody for diseases under the frame of children's immunization program, in order to know the effects of prevention and control of such diseases in this area. MethodsA total of 150 children from each of the 5 communities or administrative villages in Yongning District of Nanning City were selected for our survey between January and December 2012. The 150 children were composed of 30 children (residents, 1-6 years old, 5 children from each different age group) randomly selected from each of the four directions (east, south, west and north) and the mid-area of each community or village. The serum samples were collected to analyze the existence of poliomyelitis antibody, measles antibody, hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), and diphtheria antibody. ResultsAmong the 150 school-age children, antibody immune qualified rate was high for hepatitis B (HBV) antigen, in which the HBsAg immune qualified rate was 99.3%, and HBsAb immune qualified rate was 88.0%, showing no significant difference between boys and girls (P>0.05). All poliomyelitis Ⅰ, Ⅱ, and Ⅲ antibody positive rates reached 100.0%. Measles antibody test results were also satisfying for each age group, among whom the 2 and 3 year-olds reached a positive rate of the highest, 100%, and the 1, 4, 5, and 6 year-old children had a measles antibody positive rate of 96.0%, 84.0%, 88.0%, and 96.0%, respectively. The positive rate for diphtheria antibody was 100%. ConclusionThe antibody and antigen detection and analysis results for the children's immune program targeted diseases are generally satisfying in this area. Especially, the prevention of poliomyelitis and diphtheria is the best. However, prevention of HBV and measles is not as good. Therefore, tracking immunization coverage, promoting public awareness on immune planning, actively participating in the vaccination of children should be enhanced for further disease prevention.
