Objective The dynamic adaptive immune responses elicited by the inactivated virus vaccine
CoronaVac remain elusive. Methods In a prospective cohort of 100 healthcare professionals …

While the immunogenicity of inactivated vaccines against coronavirus disease 2019 (COVID‐
19) has been characterized in several well-conducted clinical trials, real-world evidence …

Objectives First, to describe SARS-CoV-2 T cell and antibody responses in a prospective
cohort of healthcare workers that suffered from mild to moderate COVID-19 approximately …

The appearance and magnitude of the immune response and the related factors correlated
with SARS-CoV-2 vaccination need to be defined. Here, we enrolled a prospective cohort of …

SARS-COV-2 vaccines have been shown to be efficacious primarily in healthy volunteer
populations and population level studies. Immune responses following SARS-CoV-2 …

Background A major challenge of the SARS-CoV-2 pandemic is to better define" protective
thresholds" to guide the global response. We aimed to characterize the longitudinal …

Constant efforts to prevent infections by severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) are actively carried out around the world. Several vaccines are currently …

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 …

The timing of the development of specific adaptive immunity after natural SARS-CoV-2
infection, and its relevance in clinical outcome, has not been characterized in depth …

Understanding immune memory to COVID-19 vaccines is critical for the design and optimal
vaccination schedule for curbing the COVID-19 pandemic. Here, we assessed the status of …
