Cellular and humoral immune responses are essential for COVID-19 recovery protection against SARS-CoV-2 reinfection. To date, the evaluation of has mainly focused on antibody detection, generally disregarding cellular response, or placing it in a secondary position. This phenomenon may be explained by complex nature assays needed to analyze immunity compared with technically simple automated detection antibodies. Nevertheless, large body evidence supports relevance T cell’s role SARS-CoV-2,...

The global SARS-CoV-2 pandemic has highlighted the critical importance of evaluating adaptive immunological status in both infected individuals and those who have been vaccinated. While humoral immune response extensively studied, cellular component not progressed as rapidly due to challenges developing rapid diagnostic tests for activated T cells. This study introduces a rapid, user-friendly assay aimed at addressing this need by using early expression interferon-gamma (IFN-γ) transcripts...

During the recent SARS-CoV-2 outbreak, there has been a recognized need of evaluating adaptative immunological status, not only in infected individuals, but also vaccinated population. While humoral immune response extensively assessed, cellular received less attention due to challenges transferring it into rapid diagnostic test. Consequently, is demand for development and user-friendly test detecting activated T cells. This study based on measuring interferon-gamma production as an indirect...

Abstract Background and Aims No data exists on humoral or cellular responses to mRNA vaccines in kidney transplant recipients (KTR) with HIV. We compared these HIV-positive negative KTR, as well people living HIV (PLWH) without transplantation.

Enhancing our comprehension of mRNA vaccines may facilitate the future design novel aimed at augmenting immune protection while minimising reactogenic responses. Before this is carried out, it important to determine whether adaptive immunity correlates with reactogenicity profile vaccines. We studied a large cohort that was vaccinated answer question. This an observational study real-world data. Reactogenicity data were obtained from VigilVacCOVID study. Immunogenicity (humoral and cellular)...
