A possible protective effect of seasonal influenza vaccination against the spread of the COVID-19 epidemic has been suggested.
We used publicly available data bases to explore the hypothesis as well as the effect of multiple social and environmental factors in the 20 Italian regions.
Our results suggest that vaccination against seasonal influenza might beneficially impact on incidence and severity of the novel corona virus epidemic. Population density and vehicular traffic were also moderately associated with cumulative incidence of COVID-19. None of the other variables we considered showed an effect on cumulative incidence, case fatality rate or mortality from COVID-19.
Extending influenza vaccination coverage particularly among the elderly, vulnerable individuals with specific chronic medical conditions, health care workers, and workers in other essential services, early in the upcoming 2020 influenza season, might help reduce the health impact of a second epidemic wave of COVID-19.
季节性流感疫苗接种对 COVID-19 疫情传播可能具有保护作用。
我们使用公共可用数据库来探索这一假设，以及 20 个意大利地区多种社会和环境因素的影响。
我们的结果表明，季节性流感疫苗接种可能有益于减轻新型冠状病毒疫情的发病率和严重程度。人口密度和车辆交通也与 COVID-19 的累积发病率中度相关。我们考虑的其他变量均未显示对 COVID-19 的累积发病率、病死率或死亡率有影响。
在即将到来的 2020 年流感季节，特别要扩大老年人、有特定慢性疾病的脆弱人群、卫生保健工作者以及其他基本服务部门工作人员的流感疫苗接种范围，这可能有助于减轻 COVID-19 第二波疫情对健康的影响。
