The Childhood Immunization Initiative (CII), a comprehensive response to under-vaccination among preschool-aged children, was initiated in the United States in 1993 (1). The CII established the goal of increasing vaccination coverage levels among children aged 2 years to > or = 90% by 1996 for the most critical doses of each vaccine routinely recommended for children (except hepatitis B vaccine, for which the objectives were to increase coverage to 70% by 1996 and 90% by 1998). This report presents final 1996 estimates of coverage with vaccines targeted by CII among children aged 19-35 months, which indicate that in 1996 all national vaccination coverage goals were exceeded for the routinely recommended vaccines.
儿童免疫计划（CII）是针对学龄前儿童疫苗接种率不足的一项全面应对措施，于1993年在美国启动（1）。CII设定了到1996年将2岁儿童常规推荐的每种疫苗（乙型肝炎疫苗除外，其目标是到1996年覆盖率提高到70%，到1998年提高到90%）最关键剂量的接种覆盖率提高到≥90%的目标。本报告提供了1996年19至35个月龄儿童CII目标疫苗接种覆盖率的最终估计值，表明1996年常规推荐疫苗的所有全国性接种覆盖率目标均已超额完成。
