目的：关于儿童何时以及为什么落后于推荐的疫苗接种，我们知之甚少。检查了整个生命的前2年的疫苗接种状况，以确定导致自然减员的脆弱过渡期，并确定儿童落后是因为错过了疫苗接种访视还是因为错过了同时接种疫苗的机会。方法：分析了2006-2007年全国免疫接种调查中27,083名24-35月龄儿童的疫苗接种史，以确定每个年龄患病日的疫苗接种状况，重点关注3、5、7、16、19和24个月的里程碑年龄。还评估了儿童谁落在里程碑之间的百分比和百分比谁这样做，由于缺乏疫苗接种访问相比，错过了机会，同时vaccination.Results：从一个里程碑年龄落在后面的儿童的百分比到下一个。从16个月至19个月的9%到7个月至16个月的20%不等。在3月龄至5月龄、5月龄至7月龄和16月龄至19月龄的间隔期内，错过疫苗接种访视占大多数减员，而在7月龄至16月龄的间隔期内，错过同时接种疫苗的机会占落后儿童的90%以上。必须解决错过疫苗接种访问和错过同时接种疫苗的机会的问题，以减少落后于疫苗接种的儿童人数。五分之一的儿童在7个月至16个月的时间间隔内落后-主要是由于错过了同时接种疫苗的机会-提供者应该专注于这一时间间隔，以提供所有推荐的疫苗接种。
Objective: Little is known about when-and why-children fall behind in their recommended vaccinations. Vaccination status throughout the first 2 years of life was examined to identify vulnerable transition periods that account for attrition and to determine whether children fell behind because they missed vaccination visits or because of missed opportunities for simultaneous vaccination.Methods: Vaccination histories for 27,083 children aged 24-35 Months in the 2006-2007 National Immunization Survey were analyzed to determine the vaccination status at each age ill days, focusing on the milestone ages of 3, 5, 7, 16, 19, and 24 months. Also assessed were the percentage of children who fell behind between milestones and the percentage who did so due to the lack of a vaccination visit compared to a missed opportunity for simultaneous vaccination.Results: The percentage of children who fell behind from one milestone age to the next. ranged from 9% during the interval from age 16 months to 19 months to 20% during the interval from age 7 months to age 16 months. Missed vaccination visits accounted for most attrition during the intervals from age 3 months to age 5 months, age 5 months to age 7 months, and age 16 months to age 19 months, while missed opportunities for Simultaneous vaccination accounted for >90% of the children who fell behind during the interval from age 7 months to age 16 months.Conclusions: Missed vaccination visits and missed opportunities for simultaneous vaccinations both must be addressed to reduce the number of children falling behind in their vaccinations. With one in five children falling behind during the interval from age 7 months to age 16 months-mostly as a result of missed opportunities for simultaneous vaccination-providers should FOCUS on this time interval to deliver all of the recommended vaccinations that are due.
