少数民族在欧洲疫苗试验中的代表性是一个重要的,迄今尚未解决的文献差距。本研究的目的是确定报告受试者种族人口统计学数据的欧洲疫苗试验的比例,以评估试验受试者中少数民族群体的分布(如有报告),并确定这是否代表了该国更广泛的人口。设计我们评估了临床研究中少数民族/种族群体的代表性,对2010年1月1日至2020年12月31日期间在欧洲开始的已完成疫苗试验的临床试验登记数据进行定量分析。数据来源数据收集自四个主要临床试验数据库:ClinicalTrials.gov、欧盟临床试验登记册(EUCTR)、国际标准随机对照试验编号(ISRCTN)和国际临床试验注册平台(ICTRP).ResultsA大多数临床试验未能在临床试验注册数据库上记录或报告其志愿者的种族/民族。报告的英国疫苗试验参与者并不能代表更广泛人群的种族人口统计学。人口水平的种族数据,许多欧洲国家是一个重大障碍,以确定更广泛的适用性,这些findings. ConclusionsUnder-representative少数民族群体在疫苗试验可能会影响常规疫苗接种的有效性,威胁正义和公平的原则,是嵌入在国家医学研究指南。由于缺乏人口一级的族裔数据,人们对这一问题的严重程度普遍缺乏了解,尽管文献表明这一问题值得关注。
ObjectivesThe representation of ethnic minority groups in European vaccine trials is an important and hitherto unaddressed gap in the literature. The objectives of this study were to determine the proportion of European vaccine trials that report data on the ethnic demographics of participants, to evaluate the distribution of ethnic minority groups among trial participants (where reported), and ascertain whether this is representative of the wider population of the country.DesignWe evaluated the representation of ethnic/racial minority groups in clinical research, conducting a quantitative analysis of clinical trials registry data from completed vaccine trials in Europe that commenced between 1 January 2010 and 31 December 2020.Data sourcesData were collected from four major clinical trial databases: ClinicalTrials.gov, the European Union Clinical Trials Register (EUCTR), the International Standard Randomised Controlled Trial Number (ISRCTN) and the International Clinical Trials Registry Platform (ICTRP).ResultsA majority of clinical trials failed to either record or report the race/ethnicity of their volunteers on the clinical trials registry databases. Reported participants in UK vaccine trials were not representative of the ethnic demographics of the wider population. Unavailability of population-level ethnicity data for many European countries was a significant barrier to determining the wider applicability of these findings.ConclusionsUnder-representation of ethnic minority groups in vaccine trials may have implications for the effectiveness of routine vaccinations, threatening the principles of justice and equity that are embedded in national medical research guidelines. Unavailability of population-level ethnicity data exacerbates the prevailing lack of understanding of the extent of this issue, despite literature indicating cause for concern.
