Taipei County Health Bureau
1986 Vol.2 NO.7
During the period March 11-17, a survey was conducted in 9 urban townships in Taipei County to determine immunization rates among children 12-23 months of age. Thirty clusters of 100 households each were randomly selected from township household registration offices, and interviewers visited all households in each cluster1. All household residents in the target age group, whether registered in Taipei County or townships in other counties, were included in the survey. Immunizations counted were those verified by immunization cards or health station records. Children were counted fully immunized if they received all of the following vaccines: one dose of BCG, three doses of DPT and polio, and one dose of measles.
