The Expanded Programme on Immunization has, since its inception, struggled to achieve high completion rates for child immunizations. The introduction of 2YL (second year of life) immunizations presents the programme with fresh challenges to assuring high completion rates.
Using the same procedures as those employed in the 2017 article on SMS reminders, of which this is an update, I searched the NLM database for all recent articles from developing countries on SMS reminders for reduction of vaccination dropout rates. I summarized these and earlier articles in tabular form.
The freshly reviewed articles are confirmatory of earlier studies which show an improvement in vaccination completion rates when SMS reminders are sent to mothers and other caregivers.
All of the studies reviewed were based on pilot projects. It is time, and past time, to go to scale with SMS reminders, perhaps stand alone, or as part of a larger system of electronic immunization registers. There may be potential for use of WhatsApp in dropout reduction, thus far documented only in other public health applications.
扩大免疫规划自启动以来，一直在努力实现儿童免疫接种的高完成率。第二年（2YL）免疫接种的引入给该规划确保高完成率带来了新的挑战。
采用与2017年关于短信提醒的文章相同的程序（本文是该文章的更新），我在国立医学图书馆数据库中搜索了发展中国家最近所有关于通过短信提醒降低疫苗接种漏种率的文章。我以表格形式总结了这些文章和早期的文章。
新审查的文章证实了早期研究，即向母亲和其他照料者发送短信提醒时，疫苗接种完成率会提高。
所有审查的研究均基于试点项目。现在是时候（早就该如此）扩大短信提醒的规模了，或许单独使用，或者作为更大的电子免疫登记系统的一部分。使用WhatsApp在降低漏种率方面可能具有潜力，目前仅在其他公共卫生应用中有相关记录。
