Background The immune response to COVID-19-vaccination differs between naïve
vaccinees and those who were previously infected with SARS-CoV-2. Longitudinal …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes
coronavirus disease 2019 (COVID-19), which has affected hundreds of millions of people …

Understanding the magnitude of responses to vaccination during the ongoing SARS-CoV-2
pandemic is essential for ultimate mitigation of the disease. Here, we describe a cohort of …

Hybrid immunity induced by vaccination following recovery from SARS-CoV-2 infection is
more robust than immunity induced by either infection or vaccination alone. To investigate …

Breakthrough infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-
2) variants have been reported frequently in vaccinated individuals with waning immunity. In …

Introduction The heterogeneity of the immunocompromised population means some
individuals may exhibit variable, weak or reduced vaccine-induced immune responses …

Previous studies have indicated that antibody responses can be robustly induced after the
vaccination in individuals previously infected by SARS-CoV-2. To evaluate anti-SARS-CoV …

Background To determine the dynamic SARS-CoV-2 specific antibody levels induced by 3
doses of an inactivated COVID-19 vaccine, CoronaVac. An observational, prospective …

We evaluated and compared humoral immune responses after inactivated coronavirus
disease 2019 (COVID‐19) vaccination among naïve individuals, asymptomatically infected …

Background: Vaccine mediated SARS-CoV-2 antibody responses should be carefully
evaluated. With regular follow-up in healthy individuals, we aimed to determine SARS-CoV …
