The principal goal of the Childhood Immunization Initiative (CII) is to increase, by 1996, vaccination levels for 2-year-old children to at least 90% for the most critical doses in the vaccination series (i.e., one dose of measles-mumps-rubella vaccine [MMR] and at least three doses each of diphtheria and tetanus toxoids and pertussis vaccine [DTP], oral poliovirus vaccine [OPV], and Haemophilus influenzae type b vaccine [Hib]) and to at least 70% for at least three doses of hepatitis B vaccine (Hep B). Since 1991, annual national estimates of vaccination coverage levels of preschool-aged children have been available through the National Health Interview Survey (NHIS) conducted by CDC. This report presents vaccination coverage levels of children aged 19-35 months for 1992 and provisional estimates of vaccination coverage for the combined first and second quarters of 1993 (Table 1).
儿童免疫计划（CII）的主要目标是，到1996年，将2岁儿童针对疫苗接种系列中最关键剂量的疫苗接种率提高到至少90%（即一剂麻疹-腮腺炎-风疹疫苗[MMR]以及白喉、破伤风类毒素和百日咳疫苗[DTP]、口服脊髓灰质炎病毒疫苗[OPV]和b型流感嗜血杆菌疫苗[Hib]各至少三剂），并将至少三剂乙肝疫苗（Hep B）的接种率提高到至少70%。自1991年以来，可通过疾病控制和预防中心（CDC）开展的国家健康访谈调查（NHIS）获得全国学龄前儿童疫苗接种覆盖率的年度估计数据。本报告呈现了1992年19至35个月龄儿童的疫苗接种覆盖率以及1993年第一和第二季度合并后的疫苗接种覆盖率初步估计数据（表1）。
