we deeply profiled the humoral immune response in individuals enrolled in the ChAdOx1 nCoV-19 vaccine clinical trial in South Africa performed between June and November 2020 (COV005), in which 92.9% of primary endpoint cases were caused by the beta (B.1.351) SARS-CoV-2 VOC, all ...
Ongoing clinical studies reveal that the ChAdOx1 nCoV-19 vaccine has a tolerable safety profile and is effective against symptomatic COVID-19. This vaccine may prove crucial in boosting herd immunity, averting life threatening illness, and relieving the current pandemic. In this mini re...
研究发现,在232名第一针接种ChAdOx1 nCoV-19疫苗(Oxford-AstraZeneca, 腺病毒载体疫苗)、间隔9-12周后第二针接种BNT162b2疫苗(BioNTech-Pfizer, mRNA疫苗)的接种者中,有229名接种者在第二针疫苗接种后两周较第二针接种当天的中和抗体水平显著增加。同时,研究还比较了上述混合接种方案与两针均接种同种类型方案所...

根据《自然》发表的一篇论文 Neutralizing nanobodies bind SARS-CoV-2 spike RBD and block interaction with ACE2 , 针对SARS-CoV-2的ChAdOx1 nCoV-19疫苗目前正在英国进行人体临床试验,该疫苗能引起免疫反应,并降低暴露于SARS-CoV-2的恒河猴的病毒载量。 该疫苗被发现可以预防恒河猴患上COVID-19 (新冠肺炎) ...
牛津大学的新冠病毒疫苗(腺病毒载体疫苗ChAdOx1 nCoV-19)的动物试验的论文出来了。这张图是给猴子的呼吸道灌病毒之后的结果,红色:注射过疫苗的猴子;蓝色:对照组。主要结论: 1.单次疫苗接种可在猴中诱导体液和细胞免疫应答; 2.与对照组相比,接受疫苗接种的动物的支气管肺泡灌洗液和呼吸道组织中的病毒载量显着降低...
