SARS-CoV-2 Omicron subvariants BA.2.12.1 and BA.4/5 have surged notably to become dominant in the United States and South Africa, respectively 1,2. These new subvariants carrying further mutations in their spike proteins raise concerns that they may further evade neutralizing antibodies, thereby further compromising the efficacy of COVID-19 ...
2022年5月20日 · BA.2.12.1具有强大的免疫逃逸能力。. 美国俄亥俄大学最新的研究显示，用BA.1、BA.2感染后康复人群的血清和接种2针或3针mRNA疫苗人群血清中的中和抗体做测试，发现相比奥密克戎传播最广的子变体BA.1、BA.2， BA.2.12.1具有更强的抗性。. 除了免疫逃逸能力外，研究 ...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron sublineages BA.2.12.1, BA.4 and BA.5 exhibit higher transmissibility than the BA.2 lineage<sup>1</sup>. The receptor binding and immune-evasion capability of these recently emerged variants require immediate investigation. Here, co …
2022年5月10日 · But the symptoms commonly associated with BA.2.12.1 are typically akin to those of a head cold, Dr. Russo says, explaining that sore throat, runny nose, headache, or cough should definitely prompt ...

2022年11月25日 · BNT162b2-vaccinated individuals after Omicron BA.1 breakthrough infection have strong serum-neutralizing activity against Omicron BA.1, BA.2, and previous SARS-CoV-2 variants of concern (VOCs) yet less against the highly contagious Omicron sublineages BA.4 and BA.5 that have displaced previous varia …
2022年5月18日 · Here, we describe partial ORF1ab gene target failure (pOGTF) on the cobas SARS-CoV-2 assays, defined by a ≥2-thermocycle delay in detection of the ORF1ab gene compared to that of the E-gene. We demonstrate that pOGTF is 98.6% sensitive and 99.9% specific for SARS-CoV-2 lineage BA.2.12.1, an emerging variant in the United States with spike ...
