Abstract

Introduction

Racial and ethnic disparities in COVID-19 vaccine access are well-documented; however, few studies have examined whether racial disparities are modified by other factors, including geographic location and area-level deprivation.

Methods

We conducted an observational study using the COVVAXAGE database. Medicare beneficiaries who received the COVID-19 vaccine primary series (two doses) between 01/01/2021 and 12/31/2021 were included. Racial differences in the time between doses was assessed by urbanicity using g-formula methods.

Results

We identified 11,924,990 beneficiaries (mean age = 75.4; 60 % female; 80 % White). Most beneficiaries (97.1 %) received their second vaccine on time. Delayed second doses were more common among beneficiaries who were Black (RR_delayed = 1.30, 95 %CI = 1.28–1.31) and rural (RR_delayed = 1.27, 95 %CI = 1.25–1.29) relative to White and urban beneficiaries. Racial disparities in delayed vaccinations varied in magnitude by degree of urbanicity.

Conclusions

Most beneficiaries received their second COVID-19 vaccine on time. Racial disparities were observed and shown to vary by geographic area.

美国老年人完成 COVID-19 疫苗初级系列接种所需的时间因种族、民族和地域而异。

导言：COVID-19疫苗接种中的种族和民族差异已得到充分证实；然而，很少有研究探讨种族差异是否会因其他因素（包括地理位置和地区贫困程度）而改变：我们利用 COVVAXAGE 数据库开展了一项观察性研究。研究纳入了在 2021 年 1 月 1 日至 2021 年 12 月 31 日期间接种 COVID-19 疫苗初级系列（两剂）的医疗保险受益人。使用 g 公式法评估了不同城市居民接种疫苗间隔时间的种族差异：我们确定了 11,924,990 名受益人（平均年龄 = 75.4 岁；60% 为女性；80% 为白人）。大多数受益人（97.1%）按时接种了第二针疫苗。相对于白人和城市受益人，黑人（RRdelayed = 1.30, 95 %CI = 1.28-1.31）和农村（RRdelayed = 1.27, 95 %CI = 1.25-1.29）受益人中延迟接种第二针的情况更为普遍。延迟接种疫苗的种族差异因城市化程度而异：结论：大多数受益人都按时接种了第二针 COVID-19 疫苗。结论：大多数受益人都按时接种了第二针 COVID-19 疫苗。
