CMI highlight: SARS-COV-2 antibody dynamics and B-cell memory response over-time in COVID-19 convalescent subjects
Worldwide spread of COVID-19 disease highlights the need for assessment of long-term humoral immunity in convalescent subjects. The aim of this study was to evaluate long-term IgG SARS-CoV-2 antibody response and B-cell memory response in COVID-19 convalescent subjects.
Blood samples were collected from a cohort of subjects recovering from COVID-19 disease and from healthy subjects that donated blood.
The majority of COVID-19 convalescent subjects develop IgG SARS-COV-2 antibody response that prevails a protective level over a period of up to 9-months regardless of age, gender, major blood types or clinical symptomatology. Read more
