Vaccinated people can develop stronger antibody responses against COVID-19 variants.接种疫苗的人可以产生更强的针对新冠肺炎变种的抗体反应
部分节选：
A recent study showed that vaccinated individuals can develop more robust and broadly reactive antibody responses against COVID-19 variants than the unvaccinated after an Omicron infection, which underlines the importance of COVID-19 vaccination even for people who have already been infected and for the elderly who might be exposed to infection in the future.
最近的一项研究表明，在感染后，接种疫苗的个体可以产生比未接种疫苗的个体更强的和更广泛的针对新冠肺炎变体的抗体反应，这强调了新冠肺炎疫苗接种的重要性，即使对于已经感染的人和将来可能暴露于感染的老年人也是如此。
The findings show that an Omicron infection in unvaccinated people can only induce very weak antibody responses which can react against Omicron only. By contrast, an Omicron infection in fully vaccinated individuals leads to a more potent antibody response, which is six times higher than those of unvaccinated COVID-19 patients, and the antibodies can also react against other variants, such as Beta and Delta.
该发现表明，未接种疫苗的人群中的奥米克隆感染只能诱导非常弱的抗体反应，该抗体反应只能对抗奥米克隆。相比之下，完全接种疫苗的个体中的Omicron感染会导致更强的抗体反应，比未接种疫苗的新冠肺炎患者高6倍，并且抗体也可以对其他变体产生反应，如β和δ。
The elderly people cannot assume they will not be exposed to infection sometime in the future as we know that COVID-19 infection in the elderly can be very serious and even fatal. This is completely preventable because we have good, safe and effective vaccines which are completely safe even in the elderly.
老年人不能假设他们在未来的某个时候不会受到感染，因为我们知道老年人感染新冠肺炎病毒可能非常严重，甚至是致命的。这是完全可以预防的，因为我们有良好、安全和有效的疫苗，即使对老年人也是完全安全的。
