2022年6月18日 · SARS-CoV-2 Omicron 亚系 BA.2.12.1、BA.4 和 BA.5 表现出比 BA.2 更高的传播性。新变体的受体结合和免疫逃避能力不是很清楚。2022年6月17日，北京大学谢晓亮，曹云龙，肖俊宇，中国科学院生物物理所王祥喜，中国食品药品检定研究院王佑春及南开大学沈 ...
2022年8月10日 · Abstract. The SARS-CoV-2 Omicron variant has evolved into four sub-lineages-BA.1, BA.1.1, BA.2, and BA.3-with BA.2 becoming dominant worldwide. We and others have reported antibody evasion of BA.1 and BA.2, but side-by-side comparisons of Omicron sub-lineages to vaccine-elicited or monoclonal antibody (mAb)-mediated neutralization are necessary.
2022年10月13日 · Angiotensin-Converting Enzyme 2. After the global spread of the SARS-CoV-2 Omicron BA.2, some BA.2 subvariants, including BA.2.9.1, BA.2.11, BA.2.12.1, BA.4, and BA.5, emerged in multiple countries. Our statistical analysis showed that the effective reproduction numbers of these BA.2 subvariants are greater than that of the origina ….
2023年12月6日 · BA.2.86 and XBB.1.5 show similar viral infection dynamics in the VeroE6-TMPRSS2 and H1299-ACE2 ... XBB.1.5 showed a 12-fold escape relative to BA.1, similar to the result we obtained with BA ...
2022年10月11日 · Bivalent mRNA vaccine booster induces robust antibody immunity against Omicron lineages BA.2, BA.2.12.1, BA.2.75 and BA.5
Background: BA.2.12.1, BA.4 and BA.5 subvariants of SARS-CoV-2 variant-of-concern (VOC) Omicron (B.1.1.529) are spreading globally. They demonstrate higher transmissibility and immune escape. Objectives: Determine BA.2.12.1, BA.4 and BA.5 virus plaque reduction neutralization test (PRNT) antibody titres in individuals recently vaccinated with BNT162b2 (n = 20) or CoronaVac (n = 20) vaccines or ...
2022年5月26日 · The Omicron subvariant BA.2 accounts for a large majority of the SARS-CoV-2 infection worldwide today[1][1]. However, its recent descendants BA.2.12.1 and BA.4/5 have surged dramatically to become dominant in the United States and South Africa, respectively[2][2],[3][3]. That these novel Omicron subvariants carry additional mutations in their spike proteins raises concerns that they may ...
