[Translation] A multicenter, randomized, double-blind, placebo-controlled Phase III clinical trial to evaluate the protective efficacy, immunogenicity, and safety of a recombinant respiratory syncytial virus vaccine (CHO cells) in people aged 60 years and above
评价重组呼吸道合胞病毒疫苗(CHO细胞)在单剂接种后,预防60周岁及以上人群中经逆转录-聚合酶链式反应(RT-PCR)确认因呼吸道合胞病毒亚型A(RSV-A)和/或亚型B(RSV-B)感染引起的下呼吸道疾病(LRTD)的有效性。同时,评价疫苗接种的安全性和免疫原性。
[Translation] To evaluate the effectiveness of a recombinant respiratory syncytial virus vaccine (CHO cells) in preventing lower respiratory tract disease (LRTD) caused by respiratory syncytial virus subtype A (RSV-A) and/or subtype B (RSV-B) infection, as confirmed by reverse transcription-polymerase chain reaction (RT-PCR), in people aged 60 years and older after a single dose. The safety and immunogenicity of the vaccine were also evaluated.
