To improve estimates, we conducted surveillance for SARS-CoV-2 seroprevalence among pregnant women attending their first antenatal care visit (ANC1) from June 2021 through May 2022. We administered a questionnaire to collect demographic, risk factors, and COVID-19 vaccine status information and tested dried blood spots for SARS-CoV-2 antibodies. Although &lt;1% of ANC1 participants reported having had COVID-19, monthly SARS-CoV-2 seroprevalence increased from 15.4% (95% CI: 10.5\u201321.5) in June 2021 to 65.5% (95% CI: 55.5\u201373.7) in May 2022. Although COVID-19 vaccination was available in March 2021, uptake remained low, reaching a maximum of 9.5% (95% CI: 5.7\u201314.8) in May 2022. Results of ANC1 serosurveillance provided prevalence estimates helpful in understanding this population case burden that was available through self-report and national case reports. To improve vaccine uptake, efforts to address fears and misconceptions regarding COVID-19 vaccines are needed.<\/jats:p>","DOI":"10.4269\/ajtmh.23-0726","type":"journal-article","created":{"date-parts":[[2024,3,26]],"date-time":"2024-03-26T19:25:18Z","timestamp":1711481118000},"page":"989-993","source":"Crossref","is-referenced-by-count":3,"title":["SARS-CoV-2
