Pregnant women are considered a high-risk group for COVID-19, and a priority for vaccination. Routine antenatal care provides an opportunity to track trends and factors associated with vaccine uptake. This study sought to evaluate COVID-19 vaccine uptake among pregnant women attending antenatal care in Zambia.The study was a repeated cross-sectional study in 39 public health facilities in 4 districts in Zambia from September 2021 to September 2022. Pregnant women aged 15-49 years were enrolled during their first antenatal visit. Every month, about 20 women per facility were interviewed during individual HIV counselling and testing. We estimated vaccine uptake as the proportion of eligible participants who self-reported having received the COVID-19 vaccine.
