COVID-19 (coronavirus disease 2019) vaccines induce immunity through different
mechanisms. The aim of this study is to compare the titers of specific antibodies in subjects …

Background SARS‐CoV‐2 pandemic is currently ongoing, meanwhile vaccinations are
rapidly underway in some countries. The quantitative immunoassays detecting antibodies …

Rapid and accurate measurement of the severe acute respiratory syndrome coronavirus 2
(SARS-CoV2)-specific neutralizing antibodies (nAbs) is paramount for monitoring immunity …

The true severity of infection due to COVID-19 is under-represented because it is based on
only those who are tested. Although nucleic acid amplifications tests (NAAT) are the gold …

Abstract Background Two mRNA vaccines, Pfizer-BNT162b2 and Moderna-mRNA-1273,
obtained the Emergency Use Listing by WHO for preventing COVID-19. However, little is …

Background A vast majority of the commercially available lateral flow immunoassay (LFIA) is
used to detect SARS-CoV-2 antibodies qualitatively. Recently, a novel fluorescence-based …

The extent of the COVID-19 pandemic will be better understood through serosurveys and
SARS-CoV-2 antibody testing. Dried blood spot (DBS) samples will play a central role in …

Many available SARS-CoV-2 vaccines demonstrated good humoral response, but studies
directly comparing their immunogenicity in the general population are lacking. We evaluated …

Importance In the ongoing COVID-19 pandemic, there remain unanswered questions
regarding the nature and importance of the humoral immune response against other …

Methods We evaluated two commercial assays for serological diagnosis of SARS-CoV-2
