To know Why they had no symptoms, the team conducted separate research on their T cells, which protect the body once morest infections. The researchers specifically looked at how T cells remembered viruses they had previously encountered.
When people carrying the HLA variant were first exposed to the Covid virus, their T cells were particularly ready to replicate because they remembered other seasonal viruses that they had previously pushed back.
A recent exhibition at common cold and toother coronaviruses might thus lead to fewer Covid symptoms.
This might explain why children have often escaped the worst symptoms of Covid.
The researchers hope that this study can open up new treatments or vaccines in the future. They cautioned, however, that most of the study’s participants were white, which might limit its results, and that it only covered the start of the pandemic and did not include reinfections.
