Is gravidity associated with COVID‐19 vaccination among pregnant women in Jamaica?

Abstract

In 2021, Jamaica's maternal mortality ratio doubled as a result of COVID‐19‐related deaths. Yet, COVID‐19 vaccination among pregnant Jamaican women remained low. In the United States, COVID‐19 vaccination is lower among pregnant women who have had multiple pregnancies (multigravidas) versus women who were pregnant for the first time (primigravidas). We examined whether this pattern exists in Jamaica.A cross‐sectional survey of a convenience sample of 79 pregnant Jamaican women recruited from a teaching hospital (May–July 2022) was used to assess self‐reported COVID‐19 vaccination and medical mistrust beliefs—operationalized as low vaccine confidence, government mistrust, and race‐based mistrust—by gravidity. We used modified Poisson regression to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for vaccination by gravidity, adjusting for age, education, and comorbidities.Thirty‐nine (49%) of the participants were multigravidas. Socioeconomic status was similar between multigravidas and primigravidas. COVID‐19 vaccination was lower in multigravidas (46%) than primigravidas (75%) after adjusting for age, education, and comorbidities (aPR = 0.67, 95% CI = 0.46–0.99; p = 0.044). Vaccine confidence was lower in multigravidas (p = 0.044). Government mistrust and race‐based mistrust did not differ between the two groups.In Jamaica, multigravidas may have lower COVID‐19 vaccine uptake and lower vaccine confidence compared with primigravidas. Understanding the distinct needs of pregnant subpopulations is essential for crafting effective maternal vaccination campaigns.
