Prioritisation of elderly people in COVID-19 vaccination campaigns aimed at reducing severe outcomes in this group. Using EU/EEA surveillance and vaccination uptake, we estimated the risk ratio of case, hospitalisation and death notifications in people 80 years and older compared with 25-59-year-olds. Highest impact was observed for full vaccination uptake 80% or higher with reductions in notification rates of cases up to 65% (IRR: 0.35; 95% CI: 0.13-0.99), hospitalisations up to 78% (IRR: 0.22; 95% CI: 0.13-0.37) and deaths up to 84% (IRR: 0.16; 95% CI: 0.13-0.20).
在旨在降低该人群严重后果的 COVID-19 疫苗接种活动中，优先考虑老年人。使用欧盟/欧洲经济区的监测和疫苗接种数据，我们估计了 80 岁及以上人群与 25-59 岁人群相比，病例、住院和死亡通知的风险比。对于接种率达到 80%或更高的完全接种，效果最高，病例报告率降低了高达 65%（IRR：0.35；95%CI：0.13-0.99），住院率降低了高达 78%（IRR：0.22；95%CI：0.13-0.37），死亡率降低了高达 84%（IRR：0.16；95%CI：0.13-0.20）。
