claim: functional sars-cov-2-specific immune memory persists after mild covid-19
evidence_1: furthermore, the sars-cov-2-specific memory lymphocytes exhibited characteristics associated with potent antiviral immunity: memory t cells secreted ifn-γ and expanded upon antigen re-encounter, while memory b cells expressed receptors capable of neutralizing virus when expressed as antibodies.", "these findings demonstrate that mild covid-19 elicits memory lymphocytes that persist and display functional hallmarks associated with antiviral protective immunity.", "we found that recovered individuals developed sars-cov-2-specific igg antibody and neutralizing plasma, as well as virus-specific memory b and t cells that not only persisted, but in some cases increased numerically over three months following symptom onset."
