The global SARS-CoV-2 immune landscape and population protection against emerging
variants is largely unknown. We assessed SARS-CoV-2 antibody changes in the Dominican …

To assess changes in SARS-CoV-2 spike binding antibody prevalence in the Dominican
Republic and implications for immunologic protection against variants of concern, we …

Sero-monitoring provides context to the epidemiology of severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) infections and changes in population immunity following …

Unlike genomic data, serological data have not been previously leveraged to evaluate the
SARS-CoV-2 variants circulation. In Bolivia, sustained genomic surveillance capacities were …

Background Serological assays are being deployed to monitor antibody responses in SARS-
CoV-2 convalescents and vaccine recipients. There is a need to determine whether such …

Background Comparing disease severity between SARS‐CoV‐2 variants among
populations with varied vaccination and infection histories can help characterize emerging …

Background Evaluating the performance of severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) serological assays and clearly articulating the utility of selected antigens …

Abstract SARS-CoV-2 variant B. 1.617. 2 (delta) is associated with higher viral loads and
increased transmissibility relative to other variants, as well as partial escape from polyclonal …

SARS-CoV-2 variants of concern have continuously evolved and may erode vaccine
induced immunity. In this observational cohort study, we determine the risk of breakthrough …

There is increasing evidence that the risk of SARS-CoV-2 infection among vaccinated
individuals is variant-specific, suggesting that protective immunity against SARS-CoV-2 may …
