With the ongoing spread of COVID-19, vaccination stands as an effective measure to control and mitigate the impact of the disease. However, due to the unequal distribution of COVID-19 vaccination sites, people can have different levels of spatial accessibility to COVID-19 vaccination. This study adopts an improved gravity-based model to measure the racial/ethnic inequity in transit-based spatial accessibility to COVID-19 vaccination sites in the Chicago Metropolitan Area. The results show that Black-majority and Hispanic-majority neighborhoods have significantly lower transit-based spatial accessibility to COVID-19 vaccination sites compared to White-majority neighborhoods. This research concludes that minority-dominated inner-city neighborhoods, despite better public transit coverage, are still disadvantaged in terms of transit-based spatial accessibility to COVID-19 vaccination sites. This is probably due to their higher population densities, which increase the competition for the limited supply of COVID-19 vaccination sites within each catchment area.
随着 COVID-19 的持续传播，疫苗接种是控制和减轻疾病影响的有效措施。然而，由于 COVID-19 疫苗接种点的分布不均，人们获得 COVID-19 疫苗接种的空间可达性存在差异。本研究采用改进的基于重力的模型，衡量了芝加哥大都市区基于交通的 COVID-19 疫苗接种点空间可达性的种族/民族不平等。结果表明，与白人为主的社区相比，以黑人和西班牙裔为主的社区前往 COVID-19 疫苗接种点的基于交通的空间可达性显著较低。本研究得出结论，尽管拥有更好的公共交通覆盖范围，以少数族裔为主的市中心社区在获得 COVID-19 疫苗接种点的基于交通的空间可达性方面仍处于劣势。这可能是由于其较高的人口密度，增加了每个集水区内有限的 COVID-19 疫苗接种点供应的竞争。
