At the beginning of the current pandemic, it was believed that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection would induce lifelong immunity and that reinfections would be unlikely. However, after several cases of reinfection were documented in previously infected patients, this was understood to be a false assumption, and this waning humoral immunity has raised significant concerns. Accordingly, long-term and durable vaccine-induced antibody protection against infection have also become a challenge, as several breakthroughs of COVID-19 infection have been identified in individuals who were fully vaccinated. This review discusses the current evidence on breakthrough COVID-19 infections occurring after vaccination.
在当前大流行开始时,人们认为严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)感染会诱导终身免疫,且不太可能再次感染。然而,在先前感染的患者中记录了几例再次感染病例后,人们意识到这是一个错误的假设,这种体液免疫的减弱引起了人们的高度关注。因此,针对感染的长期和持久的疫苗诱导抗体保护也成为一个挑战,因为在完全接种疫苗的个体中已经发现了几例 COVID-19 突破性感染。本综述讨论了接种疫苗后发生的突破性 COVID-19 感染的现有证据。
