5 天前 · We next compared NtAb titres (reciprocal IC 50) against SARS-CoV-2 Wuhan-Hu-1, Omicron BA.4/5, and Omicron XBB.1.5 S measured by a recombinant VSV-S-pseudotyped virus neutralization assay at the ...
2024年5月15日 · Compared with other SARS-CoV-2 variants, BA.2.86 and the JN.1 sublineage were less sensitive to vaccine-induced immune protection from the XBB.1.5 updated COVID-19 vaccine; however, we found no evidence that infection with BA.2.86 or JN.1 resulted in increased disease severity or different symptom profiles. Although less effective against the new variants, XBB.1.5 vaccination remains ...
2024年5月21日 · Background While numerous studies have evaluated the real-world performance of rapid antigen tests (RATs), data on the effect of Omicron sublineages such as XBB and reinfections on RAT performance is limited. We assessed the performance of RATs and factors associated with RAT-negative results among individuals who tested SARS-CoV-2-positive by reverse transcription-polymerase chain reaction ...
2024年5月20日 · The results showed that compound 1 exhibited potential activity with IC 50 of 17.4 μM for the delta strain and 28.5 μM for the Omicron BA.1 strain, compound 2 also showed potential activity with IC 50 of 15.3 μM for the delta strain and 22.6 μM for the Omicron
2024年5月8日 · We sought to redesign and renew the efficacy of COV2-2130 against Omicron BA.1 and BA.1.1 strains while maintaining efficacy against the dominant Delta variant. Here we show that our ...
2024年5月3日 · At T1, only 13 (12.1%) and 2 (1.9%) participants had detectable NAbs against D614G and Omicron BA.5, while no detectable NAb titers against Omicron XBB.1.5, BA.2.86, and JN.1 were observed in the serum of all elderly participants.
2024年5月7日 · Despite this, we estimated an attack rate of at least 57% during the 4th wave caused primarily by Omicron BA.1, with individuals requiring immunity from ≥2 prior infections to provide protection ...
