A study published in Science looks at pre-existing antibodies to SARS-CoV-2 in humans.
Prof Peter Openshaw, Professor of Experimental Medicine at Imperial College London, and Honorary Physician in the Department of Respiratory Medicine at the St Mary’s Campus of Imperial College NHS Trust:
“The method they use is a novel on based on flow cytometry, and may detect antibody types not seen in other studies. It is very interesting that they have detected coronavirus cross-reactive antibodies in children and adolescents, but it is not yet clear if this explains the relatively mild disease seen in younger people. It’s also not clear why older people don’t have these antibodies. One possibility is that these antibodies have been induced by common cold coronaviruses, but why they differ with age remains to be determined.”
‘Pre-existing and de novo humoral immunity to SARS-CoV-2 in humans’ by Ng et al is published in Science.
