Perceptions of COVID-19 Vaccination among Organ Transplant Recipients
TRANSPLANTATION PROCEEDINGS(2024)
摘要
Background Understanding COVID-19 vaccine hesitancy in organ transplant recipients (OTRs) is critical given clear—albeit attenuated—benefits from vaccination. Methods Adult OTRs were surveyed regarding sociodemographic data, medical history, and vaccine-related values. A novel outcome variable called the Vaccine Acceptance Composite Score (VACS) was built as the average Likert score of seven domains of vaccine confidence. To examine its association with several factors and individual adherence to COVID-19 vaccine recommendations, univariable odds ratios and relative operating characteristic areas under the curve (AUC) values were calculated. Results Of 46 OTRs included, 32.6% identified as female, 13.3% as Black, and 6.77% as Hispanic or Latino/a/x. The median age was 58 years old. 93.5% of patients were kidney transplant recipients, and 63.0% previously had COVID-19. Patients were most concerned about COVID-19 vaccine-associated risks (46.3%), its potential effect on allograft (47.6%), and motives of government officials involved with vaccine policy (55.6%). Politically conservative patients were likelier to have lower VACS, whereas those who lived with someone ≥65 years old were likelier to have higher VACS. The VACS was not significantly associated with race, income, religious beliefs, comorbidities, COVID-19 history, or influenza vaccination status. Higher VACS was associated with ≥3 and ≥4 COVID-19 immunizations. Conclusions This study highlighted political beliefs and elderly household members as correlates of vaccine acceptance among OTRs. The VACS may be a useful tool to help standardize multifaceted analyses in vaccination-focused behavioral research. In clinical practice, it could help identify individuals and groups at risk for vaccine hesitancy, who may benefit from tailored outreach and educational interventions.
