The coronavirus disease 2019 (COVID-19) pandemic has disproportionately affected certain high-risk populations, including those with underlying chronic illnesses and those who are socioeconomically disadvantaged.
Our study evaluated county-level rates of fully vaccinated populations after classifying counties based on rates of non-communicable diseases (NCDs) and socioeconomic inequities below the 25th percentile of overall distribution of counties for each measure as low, counties above the 75th percentile as high, and all other counties as medium.
Counties with higher rates of non-communicable diseases and socioeconomic disparities had lower COVID-19 vaccination coverage than did counties with lower rates of non-communicable diseases and socioeconomic disparities. Co-occurrence of high NCD and high socioeconomic vulnerability among counties in the lower half of vaccination coverage was also found for some counties.
These findings demonstrate the co-occurrence of low rates of vaccine coverage, high rates of NCDs, and high rates of socioeconomic disparities as a syndemic.
2019 年冠状病毒病（COVID-19）大流行严重影响了某些高危人群，包括患有基础慢性病和社会经济地位不利的人群。
我们的研究根据非传染性疾病（NCDs）的发病率和社会经济不平等程度对县进行分类，将发病率低于整体分布第 25 百分位数的县分为低水平，将发病率高于第 75 百分位数的县分为高水平，将其他所有县分为中水平。然后，我们评估了在这些分类基础上，完全接种疫苗的人群在县一级的比例。
与非传染性疾病和社会经济不平等程度较低的县相比，非传染性疾病和社会经济不平等程度较高的县的 COVID-19 疫苗接种率较低。在疫苗接种率较低的县中，有些县也发现了非传染性疾病和社会经济脆弱性高的同时存在。
这些发现表明，疫苗接种率低、非传染性疾病发病率高和社会经济不平等程度高同时存在是一种综合征。
