About 90% of the lives saved were among people 60 and older, with children and young adults receiving the least benefit from the jabs, researchers found.

研究人员发现，获救生命中约90%是60岁及以上的人，而儿童和年轻人从疫苗接种中获益最少。

“These estimates are substantially more conservative than previous calculations that focused mainly on the first year of vaccination, but clearly demonstrate an important overall benefit from

“这些估计比之前主要关注疫苗接种第一年的计算要保守得多，但仍然清楚地表明了疫苗接种总体上的重要益处。”

“Most of the benefits, in terms of lives and life-years saved, have been secured for a portion of the global population who is typically more fragile, the elderly,” she added.

“就挽救生命和延长寿命而言，大部分益处已为全球较脆弱的老年人群体带来保障，”她补充道。

For the new study, researchers analyzed worldwide population data to figure out how vaccination affected people who fell ill with COVID.

对于这项新研究，研究人员分析了全球人口数据，以确定疫苗接种对感染新冠肺炎的人群有何影响。

The team also assessed how many lives were saved by vaccines before and after the Omicron period, when the most virulent variant of COVID swept the world.

该团队还评估了在奥密克戎时期之前和之后，疫苗在新冠最致命变异株席卷全球时拯救了多少生命。

Results show that the most lives were saved during Omicron, about 57% of total lives saved.

结果表明，在奥密克戎期间挽救的生命最多，约占挽救总生命数的57%。

About 82% of lives saved were among people who got vaccinated prior to their infection with COVID, researchers said.

研究人员表示，约 82% 的获救生命是在感染 COVID 之前接种过疫苗的人群中。

Middle-aged adults and seniors 60 and older received the most protection from vaccination, with children and teens representing 0.01% of lives saved and young adults 20 to 29 representing 0.07% of lives saved, results show.

结果显示，中年人和60岁及以上的老年人从疫苗接种中获得了最多的保护，而儿童和青少年仅占挽救生命的0.01%，20至29岁的年轻人占挽救生命的0.07%。

These results indicate the U.S. response to the COVID pandemic was off-base when it came to children,

这些结果表明，美国对新冠疫情的应对在儿童方面是偏离正轨的，

“Both the importance of vaccines for older individuals and the fact that children were at low risk of severe complications of COVID-19 were facts that were known from very early on in the pandemic,” she wrote.

“疫苗对老年人的重要性以及儿童患新冠肺炎严重并发症的风险较低，这些都是在疫情非常早期就已知的事实，”她写道。

“Vaccines save lives and the only way to get through this pandemic was always immunity,” Gandhi continued. “It is much safer to provide immunity to an older person through a vaccine than through natural infection.”

“疫苗拯救生命，度过这场疫情的唯一方法始终是免疫力，”甘地继续说道。“通过疫苗而不是自然感染为老年人提供免疫力要安全得多。”

U.S. decisions to keep schools closed and promote vaccinations for children weren’t necessary, given these estimates, she wrote.

她写道，鉴于这些估计，美国决定保持学校关闭和促进儿童接种疫苗并不是必要的。

“At this point, a risk-based vaccination approach to boosters (with recommendations for older individuals as verified by this report) should help increase the trust in public health,” Gandhi concluded.

甘地总结道：“此时，基于风险的加强针疫苗接种方法（正如本报告所验证的，推荐给老年人）应该有助于提高对公共卫生的信任。”
