Initial results from an antibody testing study have revealed that COVID-19 antibodies remain stable in the blood of the majority of infected individuals almost two months after diagnosis and possibly longer. However, antibodies were not detectable in everyone exposed to the virus, opening discussions on how best to interpret antibody and viral tests.
The findings give answers to questions around how long people may remain immune after exposure to COVID-19 and provide insight into how different age and ethnic groups respond to infection.
The study, led by researchers and clinicians at St George’s, University of London and St George’s University Hospitals NHS Foundation Trust in collaboration with colleagues at the Liverpool School of Tropical Medicine, Mologic Ltd. and Institut Pasteur de Dakar, Sénégal, is an analysis of antibody test results from 177 individuals diagnosed with COVID-19 infection from a viral test. The work is funded by a DFID/Wellcome Trust Epidemic Preparedness coronavirus grant.
