Design and Implementation of a National Program to Monitor the Prevalence of SARS-CoV-2 IgG Antibodies in England Using Self-Testing: The REACT-2 Study
Am J Public Health. 2023 Sep 21:e1-e9. doi: 10.2105/AJPH.2023.307381. Online ahead of print.ABSTRACTData System. The UK Department of Health and Social Care funded the REal-time Assessment of Community Transmission-2 (REACT-2) study to estimate community prevalence of SARS-CoV-2 IgG (immunoglobulin G) antibodies in England. Data Collection/Processing. We obtained random cross-sectional samples of adults from the National Health Service (NHS) patient list (near-universal coverage). We sent participants a lateral flow immunoassay (LFIA) self-test, and they reported the result online. Overall, 905 991 tests were performed (28...

Identification of γ-Fagarine as a novel antiviral agent against respiratory virus (hMPV) infection
In this study, we aim to investigate the effect of γ-Fagarine on hMPV infection and explore its underlying molecular mechanisms. Vero-E6 and 16HBE cells were used as cell models. Virus replication and microcosm character were explored in Vero-E6 cells. Then, the antiviral activities were investigated by quantitative real-time PCR (RT-qPCR), western blotting (WB), and indirect immunofluorescence assays (IFAs) in Vero-E6 and 16HBE. Potential mechanisms of γ-Fagarine related to HSPG and lysosome pH were assessed in 16HBE cells. Lastly, a virus-infected mouse model was established and antiviral assay in vivo was conducted. Î...

Correlative CD4 and CD8 T-cell immunodominance in humans and mice: Implications for preclinical testing
In this study, we addressed this matter by analyzing experimentally identified epitopes based on published data curated in the Immune Epitopes DataBase (IEDB) database. We first analyzed SARS-CoV-2 spike (S) and nucleoprotein (N), which are two common targets of the immune response and well studied in both human and mouse systems. We observed a weak but statistically significant correlation between human and H-2b mouse T-cell responses (CD8 S specific (r = 0.206, p = 1.37 × 10-13); CD4 S specific (r = 0.118, p = 2.63 × 10-5) and N specific (r = 0.179, p = 2.55 × 10-4)). Due to intrinsic differences in MHC molecules acro...

Preclinical evaluation of a SARS-CoV-2 variant B.1.351-based candidate DNA vaccine
Vaccine. 2023 Sep 17:S0264-410X(23)01091-5. doi: 10.1016/j.vaccine.2023.09.021. Online ahead of print.ABSTRACTThe SARS-CoV-2 pandemic revealed the critical shortfalls of global vaccine availability for emergent pathogens and the need for exploring additional vaccine platforms with rapid update potential in response to new variants. Thus, it remains essential, for the present evolving SARS-CoV-2/Covid-19 and future pandemics, to continuously develop and characterize new and different vaccine platforms. Here, we describe an expression-optimized DNA vaccine candidate based on the SARS-CoV-2 spike protein of the Beta variant (...

Patient-reported reactogenicity and safety of COVID-19 vaccinations vs. comparator vaccinations: a comparative observational cohort study
CONCLUSION: The rate of adverse reactions after established vaccinations was roughly comparable to previous studies. Two weeks after vaccination, participants in the SARS-CoV-2 vaccination group reported more local and systemic local reactions than participants in the comparator group. In the further course, however, there were no higher odds of medical consultations in either of the two groups. Thus, altogether, we assume comparable safety.TRIAL REGISTRATION: DRKS-ID DRKS00025881 and DRKS-ID DRKS00025373.PMID:37726711 | DOI:10.1186/s12916-023-03064-6

Clinical Utility of Sero-Immunological Responses Against SARS-CoV-2 Nucleocapsid Protein During Subsequent Prevalence of Wild-Type, Delta Variant, and Omicron Variant
In conclusion, nucleocapsid antibody provides instructive clues about the immunogenicity of nucleocapsid proteins by different seroconversion rates and titers according to the severity of infection, host immune status, and different variants of concern.PMID:37724496 | DOI:10.3346/jkms.2023.38.e292
