Association between community-level political affiliation and peripartum vaccination.

BACKGROUND: Political affiliation has been associated with vaccine uptake, but whether this association holds in pregnancy, when individuals are recommended to receive multiple vaccinations, remains to be studied. OBJECTIVE: This study aimed to examine the association between community-level political affiliation and vaccinations for tetanus, diphtheria, and pertussis; influenza; and COVID-19 in pregnant and postpartum individuals. STUDY DESIGN: A survey was conducted about tetanus, diphtheria, and pertussis and influenza vaccinations in early 2021, with a follow-up survey of COVID-19 vaccination among the same individuals at a tertiary care academic medical center in the Midwest. Geocoded residential addresses were linked at the census tract to the Environmental Systems Research Institute 2021 Market Potential Index, which ranks a community in comparison to the US national average. The exposure for this analysis was community-level political affiliation, defined by the Market Potential Index as very conservative, somewhat conservative, centrist, somewhat liberal, and very liberal (reference). The outcomes were self-reported vaccinations for tetanus, diphtheria, and pertussis; influenza; and COVID-19 in the peripartum period. Modified Poisson regression was used and adjusted for age, employment, trimester at assessment, and medical comorbidities. RESULTS: Of 438 assessed individuals, 37% lived in a community characterized by very liberal political affiliation, 11% as somewhat liberal, 18% as centrist, 12% as somewhat conservative, and 21% as very conservative. Overall, 72% and 58% of individuals reported receiving tetanus, diphtheria, and pertussis and influenza vaccinations, respectively. Of the 279 individuals who responded to the follow-up survey, 53% reported receiving COVID-19 vaccination. Individuals living in a community characterized by very conservative political affiliation were less likely to report vaccinations for tetanus, diphtheria, and pertussis (64% vs 72%; adjusted risk ratio, 0.83; 95% confidence interval, 0.69-0.99); influenza (49% vs 58%; adjusted risk ratio, 0.79; 95% confidence interval, 0.62-1.00); and COVID-19 (35% vs 53%; adjusted risk ratio, 0.65; 95% confidence interval, 0.44-0.96) than those in a community characterized by very liberal political affiliation. Individuals living in a community characterized by centrist political affiliation were less likely to report vaccinations for tetanus, diphtheria, and pertussis (63% vs 72%; adjusted risk ratio, 0.82; 95% confidence interval, 0.68-0.99) and influenza (44% vs 58%; adjusted risk ratio, 0.70; 95% confidence interval, 0.54-0.92) than those in a community characterized by very liberal political affiliation. CONCLUSION: Compared with pregnant and postpartum individuals living in communities characterized by very liberal political beliefs, those living in communities characterized by very conservative political beliefs were less likely to report vaccinations for tetanus, diphtheria, and pertussis; influenza; and COVID-19, and those in communities characterized by centrist political beliefs were less likely to report vaccinations for tetanus, diphtheria, and pertussis and influenza. Increasing vaccine uptake in the peripartum period may need to consider engaging an individual's broader sociopolitical milieu.

Outpatient Use of Monoclonal Antibodies in Pregnant Individuals With Mild or Moderate Coronavirus Disease 2019 (COVID-19).

Treatment with monoclonal antibodies has been shown to significantly reduce the risk of hospitalization and disease progression among high-risk patients with coronavirus disease 2019 (COVID-19). Pregnant individuals were excluded from the original trials. In this single-center retrospective cohort study, we evaluated whether monoclonal antibody treatment in pregnant individuals is associated with decreased risk of hospitalization. Outcomes of patients who received the treatment were compared with those who were eligible but did not receive the treatment. Analyses were stratified by vaccination status. Unvaccinated pregnant patients with mild or moderate COVID-19 who received outpatient monoclonal antibodies were less likely to be admitted to the hospital (4.2% vs 15.7%, odds ratio 0.24, 95% CI 0.07-0.74), whereas among vaccinated patients, the treatment was not associated with a lower rate of hospitalization (2.3% vs 0%, P=.99).

Association of initial COVID-19 vaccine hesitancy with subsequent vaccination among pregnant and postpartum individuals.

OBJECTIVE: To examine the association between initial COVID-19 vaccine hesitancy and subsequent vaccination among pregnant and postpartum individuals. DESIGN: Prospective cohort. SETTING: A Midwestern tertiary-care academic medical center. Individuals completed a baseline vaccine hesitancy assessment from 22 March 2021 to 2 April 2021, with subsequent ascertainment of vaccination status at 3-6 months follow-up. METHODS: We used multivariable Poisson regression to estimate the relative risk of vaccination by baseline vaccine hesitancy status, and then characteristics associated with vaccination. MAIN OUTCOME MEASURES: Self-report of COVID-19 vaccination, and secondarily, consideration of COVID-19 vaccination among those not vaccinated. RESULTS: Of 456 individuals (93% pregnant, 7% postpartum) initially surveyed, 290 individuals (64%; 23% pregnant, 77% postpartum) provided subsequent vaccination status (median = 17 weeks). Of these 290 individuals, 40% (116/290) reported COVID-19 vaccine hesitancy upon enrolment, of whom 52% reported subsequent vaccination at follow-up. Few individuals transitioned during the study period from vaccine hesitant to vaccinated (10%); in comparison, 80% of those who were not vaccine hesitant were vaccinated at follow-up (aRR 0.19, 95% CI 0.11-0.33). Among those who remained unvaccinated at follow-up, 38% who were vaccine hesitant at baseline were considering vaccination, compared with 71% who were not vaccine hesitant (aRR 0.48, 95% CI 0.33-0.67). Individuals who were older, parous, employed and of higher educational attainment were more likely to be vaccinated, and those who identified as non-Hispanic black, were Medicaid beneficiaries, and were still pregnant at follow-up were less likely to be vaccinated. CONCLUSIONS: COVID-19 vaccine hesitancy persisted over time in the peripartum period, and few individuals who reported hesitancy at baseline were later vaccinated. Interventions that address vaccine hesitancy in pregnancy are needed.

Characteristics and perceptions associated with COVID-19 vaccination hesitancy among pregnant and postpartum individuals: A cross-sectional study.

OBJECTIVE: To assess the frequency and associated characteristics of COVID-19 vaccine hesitancy among pregnant and postpartum individuals. DESIGN: Cross-sectional study. SETTING: Prenatal care at a single academic tertiary care centre. POPULATION: Pregnant and postpartum individuals enrolled in prenatal care at a single academic tertiary care centre from 22 March 2021 to 2 April 2021, concurrent with state guidelines recommending COVID-19 vaccination in pregnancy. METHODS: We used logistic regression to identify characteristics associated with COVID-19 vaccine hesitancy, and adjusted for: age, parity, race, trimester of pregnancy, and chronic comorbidities. MAIN OUTCOME MEASURES: COVID-19 vaccine hesitancy, defined as uncertainty or refusal of the vaccine, despite the availability of vaccine services, in accordance with the World Health Organization (WHO) Strategic Advisory Group of Experts (SAGE) on vaccine hesitancy. RESULTS: Of the 485 individuals screened and approached, 456 (94%) enrolled and completed the survey (435/456, 95% pregnant). The frequency of COVID-19 vaccine hesitancy was 46% (95% CI 41%-51%). Sociodemographic characteristics, including non-Hispanic Black race, younger age, lower education, public health insurance receipt, parity >1, and reported substance use, were associated with a higher odds of COVID-19 vaccine hesitancy, but not clinical risk conditions. Individuals who had a family or friend vaccinated for COVID-19, prior or planned vaccination for tetanus, diphtheria and acellular pertussis (Tdap) and/or influenza, and who perceived that vaccination benefited the baby were less likely to express COVID-19 vaccine hesitancy. CONCLUSIONS: COVID-19 vaccine hesitancy was frequent among pregnant and postpartum individuals. Those who may face barriers to accessing healthcare services were more likely to report vaccine hesitancy. These results can inform interventions to increase COVID-19 vaccine uptake in pregnancy. TWEETABLE ABSTRACT: COVID-19 vaccination hesitancy is frequent among pregnant and postpartum individuals, and those who face barriers to accessing healthcare services are more likely to report COVID-19 vaccine hesitancy.

Practical considerations for pregnant women with diabetes and severe acute respiratory syndrome coronavirus 2 infection.

Epidemiologic data available so far suggest that individuals with diabetes, especially when not well controlled, are at a greater risk than the general population for severe acute respiratory syndrome coronavirus 2 morbidity such as acute respiratory distress syndrome, multiorgan failure, and mortality. Given the significant correlation between severity of coronavirus disease 2019 and diabetes mellitus and the lack of pregnancy-specific recommendations, we aim to provide some guidance and practical recommendations for the management of diabetes in pregnant women during the pandemic, especially for general obstetricians-gynecologists and nonobstetricians taking care of these patients.
