چکیده
Abstract The humoral immune response to SARS-CoV-2 is a benchmark for immunity and detailed analysis required understand the manifestation progression of COVID-19, monitor seroconversion within general population, support vaccine development. majority currently available commercial serological assays only quantify antibody against individual antigens, limiting our understanding response. To overcome this, we have developed multiplex immunoassay (MultiCoV-Ab) including spike nucleocapsid proteins endemic human coronaviruses. Compared three broadly used in vitro diagnostic tests, MultiCoV-Ab achieves higher sensitivity specificity when analyzing well-characterized sample set infected uninfected individuals. We find high coronaviruses set, but no consistent cross-reactive IgG patterns SARS-CoV-2. Here show robust, high-content-enabled, antigen-saving assay suited both monitoring vaccination studies facilitating epidemiologic screenings towards pandemic

Undoubtedly, vaccination can be one of the promising approaches to control infectious diseases such as the COVID-19 pandemic. Inactivated viral vaccines have a history of "vaccine-induced enhanced disease", which may occur when neutralizing antibodies bind to viral antigens without blocking or clearing the infection. This can cause additional inflammation through the mechanisms described for ot...
