Racial/Ethnic Variation in Veterans Health Administration COVID-19 Vaccine Uptake


Posted: 2021-11-16 20:00:00
Introduction: Equitable COVID-19 vaccine access is imperative to mitigating negative COVID-19 impacts among racial/ethnic minorities. U.S. racial/ethnic minorities have lower COVID-19 vaccination rates than Whites despite higher COVID-19 death/case rates. The Veterans Health Administration provides the unique context of a managed care system with few access barriers. This study evaluates race/ethnicity as a predictor of Veterans Health Administration COVID-19 vaccination. Methods: The cohort was composed of Veterans Health Administration outpatient users aged ≥65 years (N=3,474,874). COVID-19 vaccination was assessed between December 14, 2020 and February 23, 2021 . Multivariable logistic regressions were conducted, controlling for demographics, medical comorbidity, and influenza vaccination history. Proximity to Indian Health Service Contract Health Service Delivery Areas was tested as a moderator. Data analyses were conducted during 2021. Results: Blacks (OR=1.28, 95% CI=1.17, 1.40), Hispanics (OR=1.15, 95% CI=1.05, 1.25), and Asians (OR=1.21, 95% CI=1.02, 1.43) were more likely than Whites to receive Veterans Health Administration COVID-19 vaccinations. American Indian/Alaska Natives were less likely than Whites to receive Veterans Health Administration COVID-19 vaccinations, but only those residing in Contract Health Service Delivery Area counties (OR= 0.58, 95% CI= 0.47, 0.72). Influenza vaccine history positively predicted COVID-19 vaccine uptake (OR= 2.28, 95% CI=2.22, 2.34). Conclusions: In the Veterans Health Administration, compared with the general U.S. population, COVID-19 vaccine receipt is higher among most racial/ethnic minority groups than Whites, suggesting reduced vaccination barriers . The Indian Health Service may provide a safety net for American Indian/Alaska Native populations. Addressing vaccination access barriers in non-Veterans Health Administration settings can potentially reduce racial/ethnic disparities.

COVID-19ウイルスの広範な変異種から防御する抗体を発見。変異種間で変化の少ない受容体結合ドメイン(RBD)を標的としている。

現在のCOVID-19を引き起こすウイルスは、はるか昔の2019年12月に最初に人々を病気にしたウイルスと同じではない。現在流行している亜種の多くは、元のウイルスに基づいて開発された抗体ベースの治療薬の一部に部分的に耐性を持っている。パンデミックが続くと、必然的にさらに多くの亜種が発生し、耐性の問題は大きくなる一方だ。ワシントン大学医学部(セントルイス)の研究者らは、広範囲のウイルス亜種に対して低用量で高い保護効果を示す抗体を発見した。さらに、この抗体は、ウイルスの亜種間でほとんど違いのない部分に結合するため、この…
