Objectives

Based on the hypothesis that sources of information might affect knowledge and vaccine acceptance, our objectives were to study parental characteristics and sources of information regarding measles/measles vaccine, its relationship to correct knowledge and to administration of the measles vaccine.

Background

Although measles eradication is potentially achievable, in 2018–2019 a worldwide resurgence of measles and measles-caused deaths occurred. The main driver was incomplete or no vaccination, designated as vaccine hesitancy (VH).

Methods

A cross-sectional survey of 399 individuals dispersed all over the country was conducted. Research assistants interviewed parents with a 20-question survey which was previously validated. The questionnaire included four sections: demographics, major sources of information on measles/measles vaccine, knowledge about measles/measles vaccine, and status of child’s vaccination. Univariate and multivariate analyses explored associations between correct knowledge and VH.

Results

The majority of respondents were between the ages of 25–39 (62%). Of these, 309 (77%) vaccinated their children against measles on time, 32 (8%) vaccinations were incomplete, and 58 (15%) did not vaccinate, for a total VH of 23%. Parents < 30 years-old and those with a single-child vaccinated less frequently (p < 0.001 and p = 0.002, respectively). Internet and social-media were the major source of information for 32% regarding measles/measles vaccine and for 49% regarding the measles outbreak; both sources were negatively associated with correct knowledge (p < 0.001). In the multivariate analysis, knowledge was independently associated with timely vaccine administration (p < 0.001) and internet or social-media as sources with higher VH (OR 2.52, 95%CI 1.18–5.37 and OR 2.44, 95%CI 1.01–5.91, respectively).

Conclusions

Social-media and internet are a common source of information on measles/measles vaccine (probably on other vaccines as well), and often associated with incorrect knowledge, which relates significantly to VH. Healthcare professionals should be aware of this prevailing behavior and respond accordingly in these platforms, with the aid of experts in social-networking.

父母的信息来源和有关麻疹/麻疹疫苗知识与疫苗犹豫的知识之间的关系

目标

基于信息来源可能影响知识和疫苗接受的假设，我们的目标是研究有关麻疹/麻疹疫苗，其与正确知识的关系以及与麻疹疫苗的管理的父母特征和信息来源。

背景

尽管根除麻疹是有可能实现的，但在2018-2019年，全世界范围内再次出现了麻疹和因麻疹引起的死亡。主要驱动因素是未接种疫苗或未接种疫苗，称为疫苗犹豫症（VH）。

方法

对分布在全国各地的399个人进行了横断面调查。研究助手通过先前验证过的20个问题采访了父母。问卷包括四个部分：人口统计资料，有关麻疹/麻疹疫苗的主要信息来源，有关麻疹/麻疹疫苗的知识以及儿童的疫苗接种状况。单变量和多变量分析探索了正确知识与VH之间的关联。

结果

大多数受访者年龄在25-39岁之间（62％）。其中，有309名（77％）的孩子按时接种了麻疹疫苗，有32名（8％）的疫苗接种不完全，有58名（15％）没有接种疫苗，总VH为23％。小于30岁的父母和有独生子女的父母接种疫苗的频率较低（分别为p <0.001和p = 0.002）。互联网和社交媒体是麻疹/麻疹疫苗的主要信息来源，占32％，麻疹暴发的信息占49％；两种来源均与正确的知识负相关（p <0.001）。在多变量分析中，知识与及时接种疫苗（p <0.001）以及互联网或社交媒体具有较高的VH值（OR 2.52，95％CI 1.18-5.37和OR 2.44，95％CI 1.01-5.91，分别）。

结论

社交媒体和互联网是有关麻疹/麻疹疫苗（可能也涉及其他疫苗）的常见信息来源，并且通常与不正确的知识相关，这与VH有很大关系。医疗保健专业人员应意识到这种普遍行为，并在社交网络专家的帮助下在这些平台中做出相应反应。
