Antibodies against epitopes in S1 give the most accurate CoP against infection by the SARS‐
CoV‐2 coronavirus. Measurement of those antibodies by neutralization or binding assays …

Although there are many hypotheses for the age-related difference in the severity of COVID-
19, differences in innate, adaptive and heterologous immunity, together with differences in …

Breakthrough SARS-CoV-2 infections in fully vaccinated individuals are considered a
consequence of waning immunity. Serum antibodies represent the most measurable …

Abstract The newly identified Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-
