A systematic review and meta-analysis of the factors associating the willingness of Chinese community residents to receive COVID-19 vaccine

BACKGROUND: Amid the coronavirus disease of 2019 (COVID-19) pandemic, China's vaccination campaign is progressing in an orderly manner. In the process of vaccination, the vaccination rates in different parts of China are different, and the factors affecting people's vaccination are also different, which may be caused by some reasons affecting people's willingness to vaccinate or complex sociodemographic characteristics factors. We found that inconsistent findings on factors associated with willingness to get COVID-19 vaccination in available studies. Therefore, we conducted a meta-analysis of current factors influencing people's willingness to receive COVID-19 vaccination to assess the associated factors influencing people's COVID-19 vaccination. METHODS: The databases of CNKI, Chinese Biomedical Literature (CBM), Wanfang, VIP, PubMed, Web of Science, and Cochrane Library were searched by computer to collect the relevant literature on the factors affecting the willingness of Chinese community residents to undergo COVID-19 vaccination. After extracting the data, RevMan 5.3 and R software were used for statistical analysis. Population included in the study were Chinese community residents; outcome indicators were associated factors of willingness to get COVID-19 vaccination; COVID-19, odds ratio (OR), confidence interval (CI). Study designs were Cross-sectional study. Egger's tests was used to check potential publication bias. RESULTS: The willingness to get COVID-19 vaccination of community residents who think COVID-19 vaccine is effective is 4.10 times that of community residents who think COVID-19 vaccine is ineffective (OR =4.10, 95% CI: 3.08-5.46), and community residents who think COVID-19 vaccine is safe are 1.82 times more willing to receive COVID-19 vaccine than those who think COVID-19 vaccine is unsafe (OR =1.82, 95% CI:1.42-2.33); the willingness to get COVID-19 vaccination of community residents who think COVID-19 infection risk is high was 1.53 times that of community residents who think COVID-19 infection risk is low (OR =1.53, 95% CI: 1.43-1.64); the willingness of male community residents to vaccinate COVID-19 is 1.48 times higher than that of female community residents (OR =1.48, 95% CI: 1.23-1.76). CONCLUSIONS: The finding means that vaccination strategies need to be formulated according to the gender of community residents, propaganda of vaccination information, and dissemination of epidemic information to achieve higher levels of COVID-19 vaccination.
