Neutralizing antibodies can block infection, clear pathogens, and are essential to provide
long-term immunity. Since the onset of the pandemic, SARS-CoV-2 neutralizing antibodies …

Abstract mRNA vaccines have emerged as highly effective strategies in the prophylaxis and
treatment of diseases, thanks largely although not totally to their extraordinary performance …

The continued evolution of SARS-CoV-2 has led to the emergence of several new Omicron
subvariants, including BQ. 1, BQ. 1.1, BA. 4.6, BF. 7, and BA. 2.75. 2. Here, we examine the …

Abstract The SARS-CoV-2 Omicron variant has demonstrated enhanced transmissibility and
escape of vaccine-derived immunity. Although first-generation vaccines remain effective …

Convergent evolution of SARS-CoV-2 Omicron BA. 2, BA. 4, and BA. 5 lineages has led to
the emergence of several new subvariants, including BA. 2.75. 2, BA. 4.6. and BQ. 1.1. The …

Abstract SARS-CoV-2 Omicron BA. 1 and BA. 2 subvariants are genetically divergent. We
conducted a matched, test-negative, case-control study to estimate duration of protection of …

The unceasing circulation of SARS-CoV-2 leads to the continuous emergence of novel viral
sublineages. Here, we isolate and characterize XBB. 1, XBB. 1.5, XBB. 1.9. 1, XBB. 1.16. 1 …

Background The protection conferred by natural immunity, vaccination, and both against
symptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with …

Studies have reported reduced natural SARS-CoV-2 infection-and vaccine-induced
neutralization against omicron BA. 4/BA. 5 compared with earlier omicron subvariants. This …

The Omicron variant has been associated with reduced vaccine effectiveness (VE) against
mild disease with rapid waning. Meanwhile Omicron has also been associated with milder …
