COVID-19 vaccination coverage and intent among women aged 18-49 years by pregnancy status, United States, April-November 2021.

ABSTRACT

BACKGROUND: Pregnant and postpartum women are at increased risk for severe illness from COVID-19. We assessed COVID-19 vaccination coverage, intent, and attitudes among women of reproductive age overall and by pregnancy status in the United States. METHODS: Data from the National Immunization Survey Adult COVID Module collected during April 22-November 27, 2021, were analyzed to assess COVID-19 vaccination (receipt of ≥1 dose), intent for vaccination, and attitudes towards vaccination among women aged 18-49 years overall and by pregnancy status (trying to get pregnant, currently pregnant, breastfeeding, and not trying to get pregnant or currently pregnant or breastfeeding). Logistic regression and predictive marginals were used to generate unadjusted and adjusted prevalence ratios (PRs and aPRs). Trend analyses were conducted to assess monthly changes in vaccination and intent. RESULTS: Our analyses included 110,925 women aged 18-49 years. COVID-19 vaccination coverage (≥1 dose) was 63.2% overall (range from 53.3% in HHS Region 4 to 76.5% in HHS Region 1). Vaccination coverage was lowest among pregnant women (45.1%), followed by women who were trying to get pregnant (49.5%), women who were breastfeeding (51.5%), and all other women (64.9%). Non-Hispanic (NH) Black women who were pregnant or breastfeeding had significantly lower vaccination coverage (aPR 0.74 and 0.66, respectively) than NH White women. DISCUSSION: Our findings are consistent with other studies showing lower vaccination coverage among pregnant individuals, with substantially lower vaccination coverage among NH Black women who are pregnant or breastfeeding. Given the overlapping and disproportionate risks of COVID-19 and maternal mortality among Black women, it is critical that COVID-19 vaccination be strongly recommended for these populations and all women of reproductive age. Healthcare and public health providers may take advantage of every opportunity to encourage vaccination and enlist the assistance of community leaders, particularly in communities with low vaccination coverage.
