TL;DR: Overall, convalescent sera from patients with moderate disease had higher antibody levels and displayed a higher neutralizing ability against all strains than patients with mild or severe forms of the disease, suggesting a better cross-neutralization and higher affinity of vaccine-elicited antibodies over virus-induced antibodies.

TL;DR: P2G3, a human monoclonal antibody isolated from a previously infected and vaccinated donor, is described, which displays picomolar-range neutralizing activity against Omicron BA.1.1, BA.2 and all other current variants, and is thus markedly more potent than all authorized or clinically advanced anti-SARS-CoV-2 mAbs.

TL;DR: It is demonstrated that SARS-CoV-2 uses the SARS -CoV receptor ACE2 for entry and the serine protease TMPRSS2 for S protein priming, and it is shown that the sera from convalescent SARS patients cross-neutralized Sars-2-S-driven entry.

TL;DR: Infection with betacoronaviruses induces multi-specific and long-lasting T cell immunity against the structural N protein, and SARS-CoV-2-reactive T cells were found in individuals who had recovered from SARS or COVID-19 and in unexposed donors, although with different patterns of immunoreactivity.
