概括

这项研究发现,Ad5-nCoV疫苗不会增加参与者感染艾滋病毒的风险,即使是那些已经有5型腺病毒 (Ad5) 中和抗体的人. 这些发现支持Ad5载体疫苗的安全性.

科学领域:

疫苗学疫苗学疫苗学
传染病流行病学传染病流行病学
临床试验临床试验

背景情况:

人们对5型腺病毒 (Ad5) 载体疫苗可能增加艾滋病毒风险存在担忧.
这项研究调查了Ad5-nCoV疫苗接种与艾滋病毒感染风险之间的关联.

研究的目的:

评估Ad5-nCoV疫苗接种是否会增加艾滋病毒感染风险.
评估先前存在的Ad5中和抗体 (Nab) 对疫苗接种后艾滋病毒风险的影响.

主要方法:

第三阶段,双盲,随机,安慰剂对照试验,66个地点有44247名参与者.
参与者接受了Ad5-nCoV或安慰剂,在基线和疫苗接种后评估了HIV状况.
分析包括先前存在的Ad5 Nab,艾滋病毒流行/发病率以及人口统计学变量.

主要成果:

在Ad5-nCoV和安慰剂组接种疫苗之前,艾滋病毒流行率没有显著差异.
在接种疫苗后的6个月内,艾滋病毒发病率在接种疫苗组 (Ad5-nCoV,安慰剂,混合) 中相似.
预先存在的Ad5 Nab与艾滋病毒感染风险增加无关.

结论:

在大量多样化的人口中,Ad5-nCoV疫苗接种并没有提高短期HIV感染风险.
预先存在的Ad5 Nab的存在没有改变HIV风险,支持基于Ad5载体的疫苗安全性.

关键词:

Retrovirus Life Cycles

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...
