Since its emergence in 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-
2) has caused hundreds of millions of cases and continues to circulate globally. To establish …

Abstract Background An Israeli national taskforce performed a multi-center clinical and
analytical validation of seven serology assays to determine their utility and limitations for …

The quality and persistence of children's humoral immune response following SARS-CoV-2
infection remains largely unknown but will be crucial to guide pediatric SARS-CoV-2 …

We conducted a serological study to define correlates of immunity against SARS-CoV-2.
Compared to those with mild coronavirus disease 2019 (COVID-19) cases, individuals with …

Background Whether young adults who are infected with SARS-CoV-2 are at risk of
subsequent infection is uncertain. We investigated the risk of subsequent SARS-CoV-2 …

Background There is a need for validated and standardized severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2) quantitative immunoglobulin G (IgG) and …

Background: The combined impact of immunity and SARS-CoV-2 variants on viral kinetics
during infections has been unclear. Methods: We characterized 1,280 infections from the …

To better understand the development of SARS-CoV-2-specific immunity over time, a
detailed evaluation of humoral and cellular responses is required. Here, we characterize …

The evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) requires
ongoing monitoring to judge the ability of newly arising variants to escape the immune …

Background Understanding the longitudinal trajectory of severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) antibodies is crucial for diagnosis of prior infection and …
