[A study on immune efficacy in children immunized by hepatitis B vaccine in disease surveillance points of Fujian].
A survey was carried out for immune effect among 1-9 years old children who had been immunized with Hepatitis B vaccine from normal population in the disease surveillance points in Fujian province. According to the unified programme of the national hepatitis sero-epidemiological survey, 758 children were investigated. The samples were tested by RIA kit. The results showed as follows. Compared with the HBsAg positive rate (23.16%) among the nonvaccinated children, the HBsAg positive rate among the vaccinated children was declined to 4.79%, and the effectiveness was 79.23%. Anti-HBs positive conversion rate (S/N > or = 2.1) was from 89.29% at the 1st year to 66.67% at the 6th year of vaccination. The results indicate that the Hepatitis B vaccination possesses a good protective efficacy.
