Abstract
As Coronavirus Disease-2019 (COVID-19) vaccines became available in December 2020, increasingly more surveys were organized to examine the acceptance of vaccination, while most of them were conducted online. This study aimed to explore the difference between online and traditional on-site surveys in terms of COVID-19 vaccine acceptance. From November to December 2020, an online survey (n = 2013) and an on-site survey (n = 4,316) were conducted simultaneously in China. Multivariate logistic regression was used to identify influencing factors of acceptance, and propensity score matching (PSM) was adopted to balance the outcomes. As a result, 90.0% of the online respondents accepted COVID-19 vaccination, while it was only 82.1% in the on-site survey. After applying PSM, the acceptance rate of the on-site survey was declined to 78.6%. The age structure, residence location, education, and health status were observed as important factors in addressing vaccination acceptance, which needed to be specifically considered when designing online surveys.
Highlights
Since firstly identified in December 2019, Coronavirus Disease-2019 (COVID-19) has spread globally with a severe situation [1,2,3]
The aim of this study was to compare the online and on-site field survey results toward the public acceptance of COVID-19 vaccination, which is groundbreaking with the first largescale field survey in China and in the world to investigate the public acceptance toward COVID-19 vaccination
The present study revealed that the acceptance rate of COVID-19 vaccination among Chinese adults was as high as 90.0% in the online survey, demonstrating a minor reduction compared with the rate in the severe epidemic phase (91.9% in March 2020) [9]
Summary
Since firstly identified in December 2019, Coronavirus Disease-2019 (COVID-19) has spread globally with a severe situation [1,2,3]. By November 2020, multiple candidate vaccines had been tested in the final stage [6], such as those developed by PfizerBioNTech, Oxford-AstraZeneca, Sinopharm, and Sinovac [7, 8]. It was announced by the Chinese government on December 31, 2020 that COVID-19 vaccination would be available free of charge for Chinese citizens. This achievement has provided confidence to the global fight against COVID19, which has provided strong support to ease the pandemic in China and return to normal economic development
