Abstract

Objective: To analyze the severe cases of COVID-19 in Brazil in 2020 and compare those vaccinated and unvaccinated against influenza in invasive ventilation, admission in Intensive Care Unit (ICU), and deaths. Method: Cross-sectional study with public data from the OpenDataSUS platform confirmed severe cases for COVID-19 in Brazil in the year 2020. Data were analyzed by SPSS, from the chi-square test of independence and binary logistic regression. Results: The population was 472,688 cases and 177,640 deaths, with lethality of 37.58% in severe cases. The test of independence was highly significant in vaccinated survivors (<0.0001), and regression showed an almost twofold odds ratio for invasive ventilation, ICU admission, and death in unvaccinated cases. Conclusion: We recommend mass influenza vaccination as an adjuvant in combating the COVID-19 pandemic in Brazil.

对巴西472,688例COVID-19重症病例的分析显示,接种流感疫苗的人死亡率较低
目的:分析2020年巴西新冠肺炎重症病例,比较在有创通气、重症监护室(ICU)住院和死亡中接种和未接种流感疫苗的患者。方法:利用OpenDataSUS平台的公共数据进行交叉研究,2020年巴西确诊了新冠肺炎重症病例。数据采用SPSS进行独立性卡方检验和二元逻辑回归分析。结果:总人口为472688例,死亡177640例,重症死亡37.58%。独立性测试在接种疫苗的幸存者中非常显著(<0.0001),回归显示,在未接种疫苗的病例中,有创通气、ICU入院和死亡的优势比几乎是两倍。结论:我们建议在巴西接种大规模流感疫苗作为抗击新冠肺炎大流行的辅助疫苗。
