Abstract

We assessed the impact of the 2023/2024 COVID-19 vaccination campaign in Italy by estimating the number of averted COVID-19 severe cases (i.e. COVID-19 associated hospitalisations or deaths) between October 2023 and March 2024, in those aged ≥60 years. We estimated that 565 (95 % CI: 497–625) cases, corresponding to 2.1 % (95 % CI: 1.8–2.3) of the expected cases without a vaccination campaign, were averted. We simulated three vaccination coverage scenarios: 50 %, 75 %, 90 % (versus the observed 10.7 %), finding that 9.7 % (95 % CI: 8.5–10.7); 14.5 % (95 % CI: 12.8–16.1); and 17.4 % (95 % CI: 15.3–19.3) of the expected cases would have been averted, respectively.

我们评估了2023/2024年意大利COVID-19疫苗接种活动的影响，估计了2023年10月至2024年3月期间在年龄≥60岁的人群中避免的COVID-19重症病例数（即与COVID-19相关的住院或死亡病例）。我们估计可避免 565 例病例（95 % CI：497-625），相当于未开展疫苗接种活动时预期病例的 2.1 %（95 % CI：1.8-2.3）。我们模拟了三种疫苗接种覆盖率情况：我们模拟了三种疫苗接种覆盖率情况：50%、75% 和 90%（相对于观察到的 10.7%），结果发现预期病例的 9.7%（95% CI：8.5-10.7）、14.5%（95% CI：12.8-16.1）和 17.4%（95% CI：15.3-19.3）将分别得以避免。
