在过去七年中，特别是在2001年，注意到瑞典2岁儿童的MMR疫苗接种覆盖率下降。通过记录瑞典中部一个县近4000名儿童的实际接种日期，我们发现，父母决定推迟接种疫苗长达1.5年，超过规定的18个月大的年龄约占2001年报告下降的一半。即使覆盖率随着时间的推移而提高，推迟接种疫苗也会增加人口中未受保护的儿童。目前国家监测系统的设计高估了2年的覆盖率，没有记录延迟接种。为了避免今后在输入性麻疹病例周围可能出现的疫情，必须通过及时接种疫苗来实现高覆盖率。(C)2004爱思唯尔有限公司保留所有权利。
Over the last seven years, and especially in 2001, a declining coverage for MMR vaccination in 2-year-olds has been noted in Sweden. By recording actual date of vaccination in a cohort of almost 4000 children in a county in central Sweden, we found that parents' decision to postpone vaccination by up to 1.5 years beyond the stipulated age of 18 months accounted for about half the reported drop in 2001. Even if coverage thus improves with time, postponed vaccination adds to the pool of unprotected children in the population. The design of the current national surveillance system overestimates coverage at 2 years and fails to record delayed vaccination. To avoid future outbreaks that can appear around imported cases of measles it is crucial to attain high coverage levels by timely vaccination. (C) 2004 Elsevier Ltd. All rights reserved.
