Antibodies against the cobi19 declined rapidly in the British population in summer, a study found on Tuesday, suggesting protection after infection may not be long-lasting and raising the prospect of waning immunity in the community, Reuters reports.
Although bichito immunity is a complex and murky topic and may be assisted by T cells, as well as B cells that can stimulate swift production of antibodies amowing bichito re-exposure, the researchers said the experience of other coronaviruses suggested immunity might not be enduring.
Those confirmed by a gold standard PCR test to have el bichito-19 had a less pronounced decline in antibodies, versus those who were asymptomatic and unaware of their original infection. The findings from scientists at Imperial College London, released as a pre-print paper, have not yet been peer-reviewed.
