The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants
in the Omicron lineage has resulted in diminished Coronavirus Disease 2019 (COVID-19) …

Although mRNA vaccines encoding the spike protein of severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) prevent COVID-19, the emergence of new viral variants …

The large number of spike substitutions in Omicron lineage variants (BA. 1, BA. 1.1., and BA.
2) could jeopardize the efficacy of SARS-CoV-2 vaccines. We evaluated in mice the …

Background With the continuous emergence of new SARS-CoV-2 variants that feature
increased transmission and immune escape, there is an urgent demand for a better vaccine …

The newly emerged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
Omicron sublineages, including the BA. 2-derived BA. 2.75. 2 and the BA. 5-derived BQ. 1.1 …

This ongoing, open-label, phase 2/3 trial compared the safety and immunogenicity of the
Omicron BA. 4/BA. 5-containing bivalent mRNA-1273.222 vaccine with the ancestral Wuhan …

The recent emergence of the SARS-CoV-2 Omicron variant is raising concerns because of
its increased transmissibility and its numerous spike mutations, which have the potential to …

Recent surveillance has revealed the emergence of the SARS-CoV-2 Omicron variant (BA.
1/B. 1.1. 529) harboring up to 36 mutations in spike protein, the target of neutralizing …

The emerging SARS-CoV-2 variants of concern (VOC) harbor mutations associated with
increasing transmission and immune escape, hence undermine the effectiveness of current …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of a
global pandemic. Safe and effective COVID-19 vaccines are now available, including mRNA …
