Abstract
Vaccine willingness among the mass populace, as well as their proper knowledge and perception regarding vaccines and the vaccination process, may contribute extensively towards attaining their anticipated vaccination rates. The current study endeavored to ascertain the Bangladeshi population’s knowledge, perception, and willingness towards COVID-19 vaccination. Relevant information was collected from 1201 adults aged 18 years or older by employing an online-based survey from 1 to 30 July 2021. Descriptive statistics, the chi-square (χ2) test, and a binary logistic regression analysis were applied in order to compare the extent of knowledge and perception prevalent among different demographic groups and correlate such prevalence with respective vaccine willingness. The participants expressed mean (± standard deviation) knowledge and perception scores of 6.48 ± 1.13 out of 8 and 5.37 ± 1.22 out of 7, respectively. A multivariate analysis confirmed the significant association (p < 0.05) of gender, age, and family income with the knowledge score, whereas age and knowledge level significantly influenced perception. Current living area, family income, and age were considerable contributors to COVID-19 vaccine willingness. Overall vaccine willingness was found to be significantly curtailed by inadequate knowledge (AOR 0.514, CI 95% 0.401–0.658, p < 0.001) and perception (AOR 0.710, CI 95% 0.548–0.920, p = 0.010) among the participants. All of the concerned authorities’ efforts are warranted in order to improve public understanding, perception, and inclination towards vaccination.
Highlights
Defined as the “Severe Acute Respiratory Syndrome Coronavirus 2” (SARS-CoV-2), the seventeenth member of the coronavirus family marked its entry into human history by December 2019 as reports of a highly contagious version of pneumonia started emerging from Wuhan, Hubei province, China [1]
The current research contained four sections categorized as section A: socio-demographic variables, section B: knowledge-based eight questions, section C: perception-based questions, and section D: willingness to be vaccinated against COVID-19 related query
Among the 1144 participants who completely responded to this questionnaire-based survey, male and female were almost at a 1:1 ratio (n = 585; 51.1% and n = 559; 48.9%, respectively), illustrating a close balance of responses between both genders
Summary
Defined as the “Severe Acute Respiratory Syndrome Coronavirus 2” (SARS-CoV-2), the seventeenth member of the coronavirus family marked its entry into human history by December 2019 as reports of a highly contagious version of pneumonia started emerging from Wuhan, Hubei province, China [1]. The only genuine hope for humankind lies in the successful development of effective vaccines, as it would lead to the development of mass immunity against this pathogen. Outstanding efforts from both government- and privatefunded research organizations have culminated in the development of around 91 vaccine candidates, which are currently undergoing phase-III and phase-IV clinical trials for further evaluation of their efficacy and safety [5]. The global urgency to withstand the aggression of the COVID-19 pandemic has already led to the conditional approval of certain vaccines in many countries, including ChAdOx1 ( known as AZD1222) from the collaboration of University of Oxford-AstraZeneca (Sweden-UK), Sputnik V from Gamaleya Research Institute (Russia), BNT162b2 from the collaboration of Pfizer-BioNTech (USA-Germany) and mRNA-1273 from the government-sponsored efforts of Moderna (USA) [6]
