The comparatively milder infections with the Omicron variant and higher levels of population
immunity have raised hopes for a weakening of the pandemic. We argue that the lower …

The magnitude of immune evasion of Omicron raises the question whether it should be
considered as a distinct SARS-CoV-2 serotype. Here, we discuss lines of evidence in …

The BQ and XBB subvariants of SARS-CoV-2 Omicron are now rapidly expanding, possibly
due to altered antibody evasion properties deriving from their additional spike mutations …

The emergence and rapid spread of SARS-CoV-2 variants may affect vaccine efficacy
substantially. The Omicron variant termed BA. 2, which differs substantially from BA. 1 based …

Variant BA. 2.86 and its descendant, JN. 1, of SARS-CoV-2 are rising in incidence across
Europe and globally. We isolated recent JN. 1, BA. 2.86, EG. 5, XBB. 1.5 and earlier variants …

Summary Background In recent months, Omicron variants of SARS-CoV-2 have become
dominant in many regions of the world, and case numbers with Omicron subvariants BA. 1 …

Vaccine protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
infection wanes over time, requiring updated boosters. In a phase 2, open-label, randomized …

Large-scale vaccination campaigns have prevented countless hospitalizations and deaths
due to COVID-19. However, the emergence of SARS-CoV-2 variants that escape from …

Several studies have shown that SARS-CoV-2 BA. 1 omicron is an immune escape variant.
Meanwhile, however, omicron BA. 2 and BA. 5 became dominant in many countries and …

Serum neutralizing antibodies (nAbs) induced by vaccination have been linked to protection
against symptomatic and severe coronavirus disease 2019. However, much less is known …
