The Oxford–AstraZeneca ChAdOx1 nCoV-19 (AZD1222) vaccine, one of the earliest vaccine platforms, demonstrated 66.7% (95% confidence interval 57.4–74.0) efficacy against symptomatic ancestral SARS-CoV-2 infection25. Despite the induction of robust vaccine-specific immunity, mutations arising in the...
ChAdOx1 nCoV-19 (AZD1222) is a replication-deficient chimpanzee adenovirus vectored vaccine developed by Oxford and AstraZeneca for a disease we all know as Coronavirus, or COVID-19. Ongoing clinical studies reveal that the ChAdOx1 nCoV-19 vaccine has a tolerable safety profile and...
对照组则仅接种了一次AZD1222。 研究发现混打组接种BNT162b2 14天后的RBD抗体滴度中位数为7756.68 BAU/mL(基线为71·46 BAU/mL)。S抗原抗体滴度则为3684.87 BAU/mL(基线为98·40 BAU/mL)。 相比对照组,RBD和S抗原的IgG分别升高77.69和36.41倍。 混打组不良事件较少,混打疫苗十分安全。 这项研究指出混打疫...
We investigated ChAdOx1 nCoV-19 (AZD1222) vaccine efficacy against SARS-CoV-2 variants of concern (VOCs) B.1.1.7 and B.1.351 in Syrian hamsters. We previously showed protection against SARS-CoV-2 disease and pneumonia in hamsters vaccinated with a single
至今为止全球已有多个腺病毒疫苗进入临床阶段，其中牛津大学与阿斯利康合作开发的新冠疫苗（AZD1222）使用的就是黑猩猩腺病毒载体。据周东明教授阐述，其团队研发的黑猩猩腺病毒载体Adc68与阿斯利康牛津团队的ChAdOx1载体基因序列相似度高达98%。鉴于此前牛津新冠疫苗试验的良好保护作用，中国版黑猩猩腺病毒载体新冠疫苗有望...
Together with the fact that this dam was seronegative on GD 15, as were pups from the dam’s litter on PND 21, this result suggests that cross-contamination may have occurred. In EFD phase animals who received AZD1222, immunogenicity analyses indicated an antibody response to spike ...

The Oxford-AstraZeneca ChAdOx1 nCoV-19 vaccine (AZD1222) consists in a replication-deficient adenoviral vector, containing the SARS-CoV-2 structural surface glycoprotein antigen gene, and there are no adjuvants used in its composition. This vaccine induces generation of binding and neutralizing antibo...
Vaccines against SARS-CoV-2 are likely to be critical in the management of the ongoing pandemic. A number of candidates are in Phase III human clinical trials, including ChAdOx1 nCoV-19 (AZD1222), a replication-deficient chimpanzee adenovirus-vectored va
