Accurate antibody tests are essential to monitor the SARS-CoV-2 pandemic. Lateral flow immunoassays (LFIAs) can deliver testing at scale. However, reported performance varies, and sensitivity analyses have generally been conducted on serum from hospitalised patients. For use in community testing, evaluation of finger-prick self-tests, non-hospitalised individuals, is required.Sensitivity analysis was 276 participants. All had tested positive for by reverse transcription PCR were ≥21 days...

Full characterisation of functional HIV-1-specific T-cell responses, including identification recognised epitopes linked with antiviral would aid development effective vaccines but is hampered by HIV-1 sequence diversity. Typical approaches to identify utilising extensive peptide sets require subjects’ cell numbers that exceed feasible sample volumes. To address this, CD8 T-cells were polyclonally expanded from PBMC 13 anti-retroviral naïve subjects living HIV using CD3/CD4 bi-specific...

T cells play an important role in controlling viral replication during HIV infection. An effective vaccine should, therefore, lead to the induction of a strong and early viral-specific CD8+ cell response. While polyfunctional responses are thought be contributors antiviral response, there is evidence show that HIV- specific just small fraction total HIV-specific may absent many individuals who control replication, suggesting other HIV-1 effector subsets key players control.
