14 小時前 · We examined the anti-SARS-CoV-2 spike protein IgG antibody and neutralizing antibody titers and cellular immunity against B.1.1, BA.1, and BA.5 antigens in 73 uninfected kidney recipients and 16 ...
1 天前 · In this significant study, 20.2% of HCWs achieved seroprotection against Omicron subvariants BA.1, BA.4, and BA.5. Their immunity against Omicron subvariants was further reinforced through recommended vaccinations and the development of natural immunity from SARS-CoV-2 exposure, collectively enhancing their protection against Omicron.
5 天前 · The highly mutated SARS-CoV-2 Omicron subvariant BA.2.87.1, which emerged in South Africa in September 2023 (1, 2), has garnered global interest due to its unique constellation of many mutations in...
1 天前 · Both in vitro and in vivo studies have indicated that BA.5, compared to early Omicron BA.1 and BA.2, exhibits increased pathogenicity and immune evasion capabilities [Citation 7–10]. This raises concerns about potential changes in its impact on maternal and neonatal outcomes.
4 天前 · Importantly, XBB.1.5 has been displaced by newly emerged Omicron subvariants such as BA.2.86; however, NtAb levels in sera from vaccinated individuals have been shown to display similar or even ...
14 小時前 · Since the emergence of SARS-CoV-2 in December 2019, more than 12,000 mutations in the virus have been identified. These could cause changes in viral characteristics and directly impact global public health. The emergence of variants is a great concern due to the chance of increased transmissibility and infectivity. Sequencing for surveillance and monitoring circulating strains is extremely ...
6 天前 · Abstract: We determined neutralizing antibody levels to the ancestral Wuhan SARS-CoV-2 strain and three Omicron variants, namely BA.5, XBB.1.5, and EG.5, in a heavily vaccinated cohort of 178 adults 15–19 months after the initial vaccine series and prospectively after 4 months.
