COVID-19 vaccination strategies in the United States are informed by individual characteristics such as age and occupation. A study published in the open access journal PLOS Medicine by Sasikiran Kandula and Jeffrey Shaman of Columbia University, New York, United States suggests that including socioeconomic indicators as prioritization criteria for vaccination may help minimize severe outcomes, particularly deaths.

Efforts to reduce COVID-19 mortality rates in the US have focused on prioritizing vaccination initially for those at a higher risk of severe outcomes. The effectiveness of population-level health and socioeconomic indicators to determine risk of COVID-19 mortality is understudied. To test the hypothesis that health and socioeconomic indicators can accurately model risk of COVID-19 mortality, the researchers extracted county-level estimates of 14 indicators associated with COVID-19 mortality from public data sources. They then modeled the proportion of county-level COVID-19 mortality explained by identified health and socioeconomic indicators, and assessed the estimated effect of each predictor.

The authors found evidence for a spatial relationship between COVID-19 mortality and 9 health and socioeconomic indicators. The prevalence of chronic kidney disease and the proportion of the population resident in nursing homes had the largest individual effect on COVID-19 mortality. Although the research suggests a correlation between health and socioeconomic indicators and COVID-19 mortality, the study was limited by lags in reporting COVID-19 cases and deaths, ciprofloxacin shortage 2009 and therefore these may have been underestimated.

According to the authors, "Our findings here show that differential risks of severe outcomes from COVID-19 across populations can be in part estimated from the structures and contexts in which the outbreak occurs, for example, a population's quality of health, its access to healthcare and the disparities therein. While vaccine supply continues to be limited for most, and especially low- and middle-income, countries, these population level indicators may help inform optimal allocation.".
