Differences in SARS-CoV-2-specific immune responses have been observed between
individuals following natural infection or vaccination. In addition to already known factors …

Abstract Anti–SARS-CoV-2 vaccination has saved millions of lives in the past few years. To
maintain a high level of protection, particularly in at-risk populations, booster doses are …

Healthcare workers (HCWs) are recommended to receive at least three spike-antigen
exposures to generate basic immunity and to mediate herd protection of vulnerable patients …

Antibody studies analyze immune responses to SARS-CoV-2 vaccination and infection,
which is crucial for selecting vaccination strategies. In the KoCo-Impf study, conducted …

This study aimed at identifying factors influencing SARS-CoV-2-specific IgG antibody levels
after vaccination and/or infection. Between January 2022 and March 2023, 2000 adults (≥ …

Abstracts Objectives To assess the dynamics of the anti-SARS-CoV-2 IgG antibody levels
and their efficacy against COVID-19. Methods We conducted a longitudinal serological …

Sleep modulates the immune response, and sleep loss can reduce vaccine immunogenicity;
vice versa, immune responses impact sleep. We aimed to investigate the influence of mental …

Objectives COVID-19 vaccination is a key prevention strategy to reduce the spread and
severity of SARS-CoV-2 infections. However, vaccine-related inability to work among …

Background: This study aimed to explore how genetic variations in individuals impact
neutralization activity post-mRNA vaccination, recognizing the critical role vaccination plays …

As the COVID‐19 pandemic continues, increasingly complex vaccination and infection
histories have made it urgent to investigate the antibody dynamics in populations with hybrid …
