Small number of SARS-CoV-2 epidemic lineages did not efficiently exhibit a neutralization
profile, while single amino acid mutation in the spike protein has not been confirmed in …

Coronaviruses are enveloped, positive-stranded RNA viruses that contain the largest known
RNA genomes to date. As severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) …

The emergence of SARS-CoV-2 variants with mutations in the spike protein is raising
concerns about the efficacy of infection-or vaccine-induced antibodies. We compared …

Unrelated individuals can produce genetically similar clones of antibodies, known as public
clonotypes, which have been seen in responses to different infectious diseases, as well as …

The detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)–specific
antibodies in the serum of an individual indicates previous infection or vaccination …

One year in the coronavirus disease 2019 (COVID-19) pandemic, the first vaccines are
being rolled out under emergency use authorizations. It is of great concern that newly …

Multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines show
protective efficacy, which is most likely mediated by neutralizing antibodies recognizing the …

Several severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants have
arisen that exhibit increased viral transmissibility and partial evasion of immunity induced by …

Toward eradicating the COVID-19 pandemic, vaccines that induce high humoral and cellular
immune responses are essential. However, SARS-CoV-2 variants have begun to emerge …

Breakthrough infections by emerging SARS-CoV-2 variants raise significant concerns. Here,
we sequence-characterized the spike gene from breakthrough infections that corresponded …
