Pregnancy is an independent risk factor for severe COVID-19 illness1. World Health Organization, Centers for Disease Control and Prevention, and professional organizations recommend COVID-19 vaccination in pregnant people to prevent adverse outcomes2-4. The aim of the present study was to evaluate the uptake of COVID-19 vaccination among pregnant people.

Material and Methods:
This systematic review was carried out in accordance to PRISMA guidelines. PubMed/Medline and CINAHL databases, and the Google Scholar search engine were screened from inception to 22 March 2023 for the identification of English written, cross- sectional articles that reported COVID-19 vaccine uptake in pregnant people. A narrative synthesis approach was used to analyze studies included in this review. The risk of bias assessment was conducted according to the Joanna Briggs Institute critical appraisal tool. Registration number: INPLASY202340079.

Out of the 219 studies identified through international literature, 11 studies from seven countries (USA, Canada, Australia, Japan, Saudi Arabia, Pakistan, Israel) assessing 17579 participants (pregnant people) were included in this review5-15. All included studies were published between 2021 (n=3) and 2022 (n=8) and followed a quantitative approach using standardized questionnaires. Among the participants, only 54.9% (9650/17579) had been fully or partially vaccinated against COVID-19. The vaccination rate ranged from 1.9% to 82.1%6,9. Three of the 11 studies reported the number of vaccinations received by the vaccinated participants [87.7% (4972/5671) had received the second dose of a two-dose COVID-19 vaccine)8,9,12.

The prevalence of COVID-19 vaccine uptake among people who are pregnant is insufficient. However, these findings should be considered with caution due to small number of available studies.
