Background Understanding the dynamics of SARS-CoV-2 reinfections is crucial for public
health policy, vaccine development, and long-term disease management. However, data on …

The developmental course of antibodies produced after a SARS-CoV-2 infection has been
insufficiently investigated so far. Therefore, the aim of this study was to investigate the …

Background Antibody responses to SARS-CoV-2 can be observed as early as 14 days post-
infection, but little is known about the stability of antibody levels over time. Here we evaluate …

Background Characterizing the kinetics of the antibody response to SARS□ CoV□ 2 is of
critical importance to developing strategies that may mitigate the public health burden of …

syndrome coronavirus 2 (SARS‐CoV‐2) is of critical importance to developing strategies …

Background Reinfection with the severe acute respiratory syndrome coronavirus 2 (SARS-
CoV-2) has been documented, raising public health concerns. Risk and incidence rate of …

Background The vast majority of COVID-19 cases both symptomatic and asymptomatic
develop immunity after COVID-19 contagion. Whether lasting differences exist between …

Seroprevalence studies can contribute to a better assessment of the actual incidence of
infection. Since long-term data for Germany are lacking, we determined the seroprevalence …

Purpose Frequently the infection with coronavirus 2 (SARS-CoV-2) can be asymptomatic or
provoke only mild symptoms. These cases often remain unnoticed, so it is difficult to estimate …

There is uncertainty about the seroprevalence of anti-SARS-CoV-2 antibodies in the general
population of Austria and about the waning of antibodies over time. We conducted a …
