Social clustering of unvaccinated children in anthroposophical schools occurs, as inferred from various measles outbreaks that can be traced to these schools. However, accurate vaccination coverage data of anthroposophical schools are not widely available.
In 2012, we performed a survey to estimate the vaccination coverage in three different grades of 11 anthroposophical schools in Gelderland, The Netherlands. We also gauged the opinion on childhood vaccination of the parents and compared these with the results of a national survey. In 2014, we were also able to obtain the registered total vaccination coverage per school from the national vaccination register to compare this with our survey data.
The self-reported MMR vaccination coverage (2012) in the three grades of the schools in our study was 83% (range 45-100% per school). The registered total vaccination coverage (2014) was 78% (range 59-88% per school). The 95% confidence intervals of the two different vaccination coverages overlap for all schools. The parents in this study were less convinced about the beneficial effect of vaccinations and more worried about the possible side effects of vaccination compared with parents in general.
Despite high overall vaccination coverage, the WHO goal to eliminate measles and rubella will not easily be achieved when social clustering of unvaccinated children in anthroposophical schools remains.
从多起可追溯至人智学学校的麻疹疫情中可推断出，未接种疫苗的儿童在人智学学校中存在社交聚集现象。然而，人智学学校准确的疫苗接种覆盖率数据并不广泛可得。
2012年，我们开展了一项调查，以估算荷兰海尔德兰省11所人智学学校三个不同年级的疫苗接种覆盖率。我们还评估了家长对儿童疫苗接种的看法，并将其与一项全国性调查的结果进行比较。2014年，我们还能够从国家疫苗接种登记处获取每所学校登记的总疫苗接种覆盖率，以便将其与我们的调查数据进行比较。
我们研究中学校三个年级自我报告的MMR疫苗接种覆盖率（2012年）为83%（每所学校范围为45%-100%）。登记的总疫苗接种覆盖率（2014年）为78%（每所学校范围为59%-88%）。所有学校两种不同疫苗接种覆盖率的95%置信区间相互重叠。与一般家长相比，本研究中的家长对疫苗接种有益效果的信服度较低，且更担心疫苗接种可能产生的副作用。
尽管总体疫苗接种覆盖率较高，但只要未接种疫苗的儿童在人智学学校中的社交聚集现象仍然存在，世界卫生组织消除麻疹和风疹的目标就难以轻易实现。
