Despite vaccination and antiviral therapies, immunocompromised individuals are at risk for
prolonged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, but the …

There is an urgent need to understand the nature of immune responses against SARS-CoV-
2, to inform risk-mitigation strategies for people living with HIV (PLWH). Here we show that …

In some instances, unsuppressed HIV has been associated with severe COVID-19 disease,
but the mechanisms underpinning this susceptibility are still unclear. Here, we assessed the …

Human infection challenge permits in-depth, early, and pre-symptomatic characterization of
the immune response, enabling the identification of factors that are important for viral …

The effect of host immune status on severe acute respiratory syndrome coronavirus 2 (SARS-
CoV-2) infection remains unknown. Here, we report the first case of coronavirus disease …

Cellular and humoral immunity to SARS-CoV-2 is critical to control primary infection and
correlates with severity of disease. The role of SARS-CoV-2-specific T cell immunity, its …

Background The duration of humoral and T and B cell response after the infection of severe
acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains unclear. Methods We …

Importance Data are limited on whether patients with breakthrough COVID-19 infection have
the potential to significantly contribute to the spread of SARS-CoV-2. Objective To compare …

Background: Limited data are available on the long-term clinical and immunologic
consequences of SARS-CoV-2 infection in people with HIV (PWH). Methods: We measured …

Background Understanding mid-term kinetics of immunity to SARS-CoV-2 is the cornerstone
for public health control of the pandemic and vaccine development. However, current …
