INTRODUCTION: Pregnant women have a difficult choice about the COVID- 19 vaccination. We performed a systematic review and meta-analysis to evaluate the acceptance of a coronavirus disease 2019 (COVID-19) vaccine among pregnant women and its determinants. METHOD: We searched the bibliographic databases (Scopus, Medline, and Web of Science) for the relevant studies from 1 January 2020 to 11 July 2021. We pooled the prevalence of vaccine acceptance among pregnant women using a random-effects model and conducted subgroup analyses to explore its determinants. The result was expressed as a prevalence percentage with 95% CIs. RESULTS: We found ten studies that were suitable, with 16696 participants from 32 countries. COVID-19 vaccination acceptability in pregnant women was 54 percent globally (95 percent CI, 45 percent, 62 percent), with significant heterogeneity (I2= 99.05 percent, p <0.001). The pooled adjusted OR of COVID-19 vaccine acceptance in pregnant women with age >35 years, high education and income levels, and knowledge scores on COVID-19 infection were 1.17, 1.03, 1.18, and 2.55, respectively. CONCLUSION: About half of pregnant women accepted the COVID-19 vaccine. A high knowledge score on COVID-19 infection had an effective role to increase this acceptance. To promote vaccine knowledge, appropriate planning should be done by the health policy-makers.
