Background: The coronavirus disease (COVID-) pandemic has posed increasing challenges to global health systems. Vaccination against COVIDcan e ectively prevent the public, particularly healthcare workers (HCWs), from being infected by this disease.Objectives: We aim to understand the factors influencing HCWs' acceptance of COVID-vaccines.Methods: We searched PubMed, Embase and Web of Science to collect literature published before May , , about HCWs' acceptance of COVID-vaccines. The Newcastle-Ottawa quality assessment scale was used to assess the risk of bias and the quality of the included studies. We utilized Stata . software for this meta-analysis with a random-e ects model, and odds ratios (ORs) with % confidence intervals (CIs) were reported. This meta-analysis was conducted in alignment with the preferred reporting items for systematic review and meta-analysis (PRISMA) guideline.Results: Our meta-analysis included articles with , HCWs involved. The research showed that the acceptance of vaccines had significantly increased among HCWs compared to non-HCWs (OR = . , % CI: . -. ). A willingness to undergo COVID-vaccination was observed in % ( % CI: . -. ) of HCWs. Among the HCWs involved, doctors showed a generally increased intention to be vaccinated compared with nurses (OR = . , % CI: . -. ). Additionally, males were found to hold more positive attitudes toward vaccination than females (OR = . , % CI: . -. ). When the e ectiveness of COVID-vaccines was improved, the vaccination acceptance of HCWs was greatly increased accordingly (OR = . , % CI: . -. ). The HCWs who were willing to vaccinate against seasonal influenza showed an increased acceptance of COVID-vaccines (OR = . , % CI: . -. ). Our study also showed that HCWs who were willing to be vaccinated against COVIDexperienced a reduced rate of severe acute respiratory syndrome coronavirus (SARS-CoV-) infection (OR = . , % CI: . -. ).
