从2019年末到现在,已有超过2.63亿人确诊新冠病毒,超过5百万人的死亡跟新冠病毒有关。目前WHO将新冠病毒的变异株分为高关注变异株(variants of concern,VOCs)、需留意变异株(variants of interest,VOIs)和…
These variants are categorized as the variant of interest (VOI), variant of concern (VOC), and variant under monitoring (VUM). As of September 15, 2021, there are four SARS-CoV-2 lineages designated as the VOC (alpha, beta, gamma, and delta variants). VOCs have increased transmissibility...
然而,免疫逃脱的SARS-CoV-2变体的出现是疫苗有效性的一大挑战。鉴于这一持续进化,一个重要问题是何时以及如何更新SARS-CoV-2疫苗,这与季节性流感病毒类似,季节性流感病毒的抗原性漂移需要定期更新疫苗。 近段时间,Karlijn Straten教授...
该抗体组合的发现与鉴定对应对未来潜在的新变异株以及其他冠状病毒大流行方面具有重要的储备价值,同时有助于指导新一代通用新冠疫苗的研发。 近日,该研究成果以题为“Three SARS-CoV-2 antibodies provide broad and synergistic neutralizatio...
世界卫生组织从2020年1月起一直在监测和评估全球新冠病毒的变异,建立了区分新出现的SARS-CoV-2变体的分类系统:Variants of Concern (VOCs)和Variants of interest(VOIs)。 如Alpha (B.1.1.7)、Beta (B.1.351)、Gamma (P.1)和Delta (B.1.617.2),均与传播性和毒力增强有关,被列为"令人担忧的变异株"(Vari...
and the number of viruses hit by missiles is estimated according to the immune escape ability [https://aci.health.nsw.gov.au/covid-19/critical-intelligence-unit/sars-cov-2-variants]. This cartoon depicts the characteristics including infectivity and immune escape ability of these VOCs. Infectivity...
major lineages, such as variants of concern (VOCs), are generated, we contrast the evidence for the chronic infection model underlying the emergence of VOCs with the possibility of an animal reservoir playing a role in SARS-CoV-2 evolution, and conclude that the former is more likely. We ...

We assessed the longevity and cross-reactive breadth of serum antibodies against SARS-CoV-2 variants of concern (VOCs), including Omicron. Results The binding anti-Spike IgG antibodies remained within the reported putative levels for at least 360 days and were cross-neutralising against Beta, Gamma...
