Social determinants of health and vaccine uptake in pregnancy: Disparities in a diverse, predominately foreign-born population.

OBJECTIVE: To identify discrepancies in influenza, Tdap, and COVID-19 vaccine uptake and offer rates among pregnant individuals across various social determinants of health including race, ethnicity, foreign-born status, education level, and health insurance coverage, highlighting potential interventions to improve vaccine uptake in pregnancy. METHODS: An IRB-approved cross-sectional survey was conducted on the postpartum floor of a large urban hospital in South Florida. Between July to September 2021, 359 participants consented and answered questions on their demographics, social background, and influenza, Tdap, and COVID-19 vaccine history. RESULTS: Most participants identified as White (67.7 %), Hispanic (67.4 %), and foreign-born (68.5 %) with an average age of 29.7 ± 6 years. There was a significant difference in mean vaccine between White (1.3) and Black individuals (0.9, p = 0.002). Mean uptake was significantly higher in foreign-born individuals (1.3) compared to US-born (0.9, p < 0.001). Mean uptake was significantly higher for those with graduate (1.7) and college (1.4) degrees compared to those with a high school degree (1.0) or less than high school (1.0, p < 0.0001). CONCLUSION: Significant differences in the uptake and offer rates of influenza, Tdap, and COVID-19 vaccines were observed across a variety of social determinants including educational attainment, employment, insurance, and median income of the zip code of primary residence.

Vaccination in pregnancy: Healthcare provider attitudes and practices.

OBJECTIVE: To assess provider attitudes and practices regarding vaccination in pregnancy to discern strategies to increase vaccination rates in pregnancy, given that in the USA, various healthcare organizations recommend that pregnant individuals be vaccinated against influenza, pertussis, and SARS-CoV-2, but vaccination rates among gravidas remain suboptimal across these vaccines. METHODS: An Institutional Review Board-approved survey was disseminated to obstetric healthcare providers by email from June through October 2021. Questions assessed provider demographics, attitudes, and practices surrounding vaccination in pregnancy. A total of 192 providers consented, 179 initiated the survey, and 153 completed it entirely. Statistical software (SAS) was used to perform descriptive statistics. RESULTS: All providers strongly agreed/agreed that all pregnant individuals should receive vaccines in pregnancy. Following patient vaccination consent, 13% reported needing to refer patients to alternative sites for vaccine administration. Following patient vaccination decline, 13% did not determine reasons for refusal, 30% did not re-counsel at subsequent visits, and 92% did not ask another staff member to counsel the patient. CONCLUSION: Despite provider support for maternal immunization, uptake of vaccines in gravidas remains suboptimal, demonstrating a gap between provider recommendations and patient uptake. These data highlight opportunities for intervention regarding counseling and vaccine availability to increase vaccine uptake in pregnancy.
