“…We tested over 11,000 anonymised, stored historic antenatal serum samples, given at two north-west London NHS trusts in 2019 and 2020, for total antibody to SARS-CoV-2 receptor binding domain (anti-RBD). Estimated prevalence of seroreactivity increased from 1% prior to mid-February 2020 to 17% in September 2020. …”

“…The first SARS-CoV-2 vaccine was made available in Europe at the end of 2020. 202 volunteers from the vicinity of the University of Applied Sciences Wiener Neustadt took part in this study; their IgG levels recognizing the RBD of SARS-CoV-2 were determined. The aim was to evaluate the SARS-CoV-2 titer levels of vaccinated, recovered and vaccinated plus recovered persons. …”

“…For SARS-coV2, the focus is generally for understanding such coevolution on the virus spike protein, since it demonstrates high mutation rates compared to other genome regions, particularly in the receptor-binding domain (RBD). Viral sequences of the SARS-coV2 19B (S) clade and variants of concern from different continents were investigated, with a focus on the A.29 lineage, which presented with different mutational patterns within the 19B (S) lineages in order to learn more about how SARS-coV2 may have evolved and adapted to widely diverse populations globally. …”

“…ZF2001 is a recombinant protein vaccine based on SARS-CoV-2 receptor-binding domain (RBD) subunit which contains aluminum adjuvant. In order to advance our research on ZF2001 into clinical trial, we investigated the general toxicity and immunogenicity of ZF2001 in cynomolgus monkeys and assessed the possible target organs for vaccine-induced toxicity. …”

Our results suggest that developing an early and robust neutralizing response against SARS-CoV-2 may increase survival probability in critical patients.…”

“…After boost, the longer interval results in a higher magnitude and a more mature phenotype of RBD-specific B cells. While the two geographically distinct cohorts present quantitative and qualitative differences in T cell responses at baseline and after priming, the second dose led to convergent features with overall similar magnitude, phenotype, and function of CD4(+) and CD8(+) T cell responses at post-boost memory time points. …”
