The SARS‐CoV‐2 omicron variant (B. 1.1. 529) was first identified in Botswana and South
Africa, and its emergence has been associated with a steep increase in the number of SARS …

The continuous evolution of SARS-CoV-2 generated highly mutated variants able to escape
natural and vaccine-induced primary immunity. The administration of a third mRNA vaccine …

Antibody response following Omicron infection is reported to be less robust than that to other
variants. Here we investigated how prior vaccination and/or prior infection modulates that …

We examined the immune response in subjects previously infected with SARS-CoV2 and
infection-naïve 9 months after primary 2-dose COVID-19 mRNA vaccination and 3 months …

Summary Heterologous ChAdOx1-BNT162b2 vaccination induces a stronger immune
response than BNT162b2-BNT162b2. Here, we investigated the molecular transcriptome …

Patients with chronic lymphocytic leukemia (CLL) treated with B-cell pathway inhibitors and
anti-CD20 antibodies exhibit low humoral response rates following SARS-CoV-2 …

INTRODUCTION: With the emergence of newer SARS-CoV-2 variants and their substantial
effects on the levels and duration of protection against infection, an understanding of these …

The continuous evolution of SARS-CoV-2 generated highly mutated variants, like omicron
BA. 1 and BA. 2, able to escape natural and vaccine-induced primary immunity,. The …

Omicron is currently the dominant SARS-CoV-2 variant and several sublineages have
emerged. Questions remain about the impact of previous SARS-CoV-2 exposure on cross …

COVID-19 vaccines can be the tugboats for preventing SARS-CoV-2 infections when they
are practical and, more importantly, without adverse effects. However, the reality is that they …
