研究发现,COVID-19接种疫苗将青少年的长期症状减少36%。 COVID-19 vaccination reduces long-term symptoms in teens by 36%, study finds.

对1 200多名12至17岁青少年进行的一项新研究发现,接种COVID-19疫苗使长期症状的风险比未接种疫苗的同龄人减少36%,接种疫苗的青年有20.7%的机会长期接种COVID,而未接种疫苗的青年有13.3%。 A new study of over 1,200 adolescents aged 12 to 17 finds that COVID-19 vaccination reduces the risk of long-term symptoms by 36% compared to unvaccinated peers, with vaccinated youth facing a 20.7% chance of long COVID versus 13.3% among unvaccinated participants. 这项研究在2022年2月至2024年11月的Omicron 浪潮期间进行,研究将感染前6个月内的疫苗接种与降低风险联系起来,即使根据性和症状发作情况作了调整。 Conducted during the Omicron wave from February 2022 to November 2024, the research links vaccination within six months before infection to lower risk, even after adjusting for sex and symptom onset. 涉及60个以上地点的RECOVER-儿科试验结果表明,疫苗接种有助于通过多种途径预防长期COVID。 The findings, from the RECOVER-Pediatrics trial involving 60+ sites, suggest vaccination helps prevent long COVID through multiple pathways. 同时,对400,000多名儿童和青少年进行单独分析后发现,再感染几乎是长期COVID风险的两倍,影响到所有年龄组,不论接种疫苗与否或最初的疾病严重程度如何,都持续存在。 Meanwhile, a separate analysis of over 400,000 children and teens shows reinfection nearly doubles the risk of long COVID, affecting all age groups and persisting regardless of vaccination or initial illness severity.
