Abstract

PURPOSE

The study examined Covid-19 vaccinations intentions among literate Ghanaians and how it is been influenced by vaccine mistrust and the fear of the unforeseen side effects.

DESIGN/METHODOLOGY/APPROACH: We used cross sectional data collected from 223 respondents by means of questionnaire disseminated through social media from 16th to 20th April, 2021. Likert-scale questions were asked regarding the knowledge, attitudes and perceptions of literate Ghanaians towards COVID-19 vaccines. Kruskal-Wallis and sample t-test were performed to ascertain the differences in vaccination intentions between key socioeconomic variables. A pairwise correlation was performed to examine the relationship between vaccination intensions and fear of the unforeseen, mistrust of the vaccine and concerns of profiteering. Finally, a binary probit regression model was fitted to examine the predictive effect of key variables on respondent's vaccination intentions.

FINDINGS

The results revealed a relatively low level of knowledge about the safety and efficacy of the COVID-19 vaccines. The sample t-test showed that males have a relatively positive attitude towards the COVID-19 vaccines than females at 5% level of significance. Mistrust of vaccine safety and efficacy have a significant negative influence on vaccination intensions at 1% significance level.

ORIGINALITY/VALUE: This study provides the Ghanaian government and other stakeholders with useful information to aid in educational campaigns on the safety and effectiveness of the COVID-19 vaccine. More campaign efforts towards females could help increase uptake given their relatively poor attitudes towards the vaccine.

摘要

目的

本研究考察了加纳有读写能力的人群对 COVID-19 疫苗的接种意愿,以及疫苗不信任和对未知副作用的恐惧如何影响这种意愿。

设计/方法/途径:我们使用了 2021 年 4 月 16 日至 20 日通过社交媒体分发的 223 名受访者的横断面数据。使用李克特量表询问了有读写能力的加纳人对 COVID-19 疫苗的知识、态度和看法。采用克鲁斯卡尔-沃利斯检验和样本 t 检验来确定关键社会经济变量对疫苗接种意愿的差异。进行了成对相关分析,以检验疫苗接种意愿与对未知的恐惧、对疫苗的不信任和对盈利的担忧之间的关系。最后,拟合了二元概率回归模型,以检验关键变量对受访者接种意愿的预测作用。

发现

结果显示,关于 COVID-19 疫苗的安全性和有效性的知识水平相对较低。样本 t 检验表明,男性对 COVID-19 疫苗的态度比女性相对积极,在 5%的显著性水平上。对疫苗安全性和有效性的不信任对疫苗接种意愿有显著的负面影响,在 1%的显著性水平上。

原创性/价值:本研究为加纳政府和其他利益相关者提供了有关 COVID-19 疫苗安全性和有效性的有用信息,以帮助开展教育宣传活动。针对女性开展更多的宣传活动可能有助于提高接种率,因为她们对疫苗的态度相对较差。
