Vaccination coverage is an important performance indicator of any national immunisation programme (NIP). To monitor the vaccination coverage in the Netherlands, an electronic national immunisation register called ‘Præventis’ was implemented in 2005. Præventis has a link with the population register and can produce letters of invitation for the NIP, register and validate administered vaccinations. The database is used to monitor the vaccination process, produce reminder letters, control the stock of vaccines and provides information used for paying the fees to the different executive organisations involved. Præventis provides a crucial tool for the evaluation of the NIP by producing (sub)national vaccination coverage estimates with high accuracy and allowing additional research: identifying populations at high risk for low coverage based on existing data, conducting specific studies where individuals included in the immunisation register are approached for further research, using vaccination coverage data for the interpretation of (sero)surveillance data, and linking the immunisation register with disease registers to address vaccine safety or vaccine effectiveness. The ability to combine Præventis data with data from other databases or disease registers and the ability to approach individuals with additional research questions offers opportunities to identify areas of priority for improving the Dutch NIP.
疫苗接种覆盖率是任何国家免疫规划（NIP）的重要绩效指标。为了监测荷兰的疫苗接种覆盖率，2005 年实施了一个名为“Præventis”的电子国家免疫登记系统。Præventis 与人口登记系统相连，可以为 NIP 发送邀请信，登记和验证已接种的疫苗。该数据库用于监测疫苗接种过程，发送提醒信，控制疫苗库存，并提供用于向相关执行组织支付费用的信息。Præventis 通过提供（子）国家疫苗接种覆盖率的准确估计值，为 NIP 的评估提供了重要工具，并允许进行额外的研究：根据现有数据确定覆盖率低的高风险人群，在免疫登记册中包含的个人进行进一步研究的特定研究，使用疫苗接种覆盖率数据解释（血清）监测数据，以及将免疫登记册与疾病登记册联系起来，以解决疫苗安全性或疫苗有效性问题。将 Præventis 数据与其他数据库或疾病登记册的数据相结合的能力，以及提出其他研究问题的能力，为确定优先领域提供了机会，以改善荷兰的 NIP。
