Background Incomplete vaccination in Australia is greatly due to vaccine hesitancy, which is driven by multiple factors. Studies analysing the effect of behavioural 'nudges' on vaccine uptake have shown promising results. Although there is some evidence for positively framed SMS vaccine messages, evidence is lacking for loss-based framed messages which may be highly effective but may paradoxically risk increasing vaccine hesitancy. This pilot study aimed to evaluate the effect of loss-based framed SMS messages on vaccine hesitancy. Methods This single-blinded randomised controlled trial enrolled pregnant women from antenatal clinics in King Edward Memorial Hospital, Perth, WA which delivers approximately 6000 higher-risk infants per year. Participants were randomised to receive either a loss-based framed SMS message warning of the risks of failure to vaccinate, or a sham SMS message unrelated to vaccination, and were asked to complete the short-scale vaccine hesitancy questionnaire before and after the intervention. Discussion The application of behavioural sciences through SMS-reminders has the potential to improve vaccination rates. There are difficulties in engaging with parents of newborns about vaccine hesitancy. Further research is warranted using other approaches to recruitment.

短信服务（SMS）提醒对新生儿父母儿童健康的影响：一项随机对照试验的试验。

背景技术澳大利亚的疫苗接种不完全很大程度上是由于疫苗的犹豫不决，这是由多种因素驱动的。分析行为“微动”对疫苗摄取的影响的研究显示出令人鼓舞的结果。尽管有一些证据表明对SMS疫苗消息采用了正构架，但对于基于丢失的帧疫苗仍缺乏证据，这种消息可能非常有效，但可能会增加疫苗犹豫的风险。这项初步研究旨在评估基于损失的带框SMS消息对疫苗犹豫的影响。方法这项单盲随机对照试验纳入了华盛顿州珀斯金爱德华纪念医院产前诊所的孕妇，该孕妇每年分娩约6000名高危婴儿。参加者被随机分为两组，分别接受以疫苗接种为基础的有框框的短信提示未接种疫苗的风险或与疫苗接种无关的假短信，并要求他们在干预前后填写短期疫苗犹豫问卷。讨论通过SMS提醒器应用行为科学具有提高疫苗接种率的潜力。与新生儿的父母就疫苗犹豫问题进行沟通有困难。有必要使用其他招募方法进行进一步研究。与新生儿的父母就疫苗犹豫问题进行沟通有困难。有必要使用其他招募方法进行进一步研究。与新生儿的父母就疫苗犹豫问题进行沟通有困难。有必要使用其他招募方法进行进一步研究。
