It's a monoclonal antibody treatment (not a vaccine) that provides antibodies to the COVID-19 virus for up to six months. That . It is also possible that the lack of decline in influenza titres was due to boosting through exposure to influenza antigens. Normally a fully vaccinated person will produce COVID-19 antibodies, and those antibodies should show up on an antibody test. All analyses were conducted using SAS v.9.4 (SAS Institute) and Prism v.8.4 (GraphPad), and Pvalues of less than 0.05 were considered significant. Our data suggest that SARS-CoV-2 infection induces a germinal centre response in humans because long-lived BMPCs are thought to be predominantly germinal-centre-derived7. c, Paired frequencies of S-binding BMPCs among IgG-secreting (left) and IgA-secreting (right) BMPCs from convalescent individuals 7 months and 11 months after symptom onset.

Overall, our data provide strong evidence that SARS-CoV-2 infection in humans robustly establishes the two arms of humoral immune memory: long-lived BMPCs and memory Bcells. Nature 388, 133134 (1997). Epidemiol. Nature. Frequencies of anti-S IgG BMPCs showed a modest but significant correlation with circulating anti-S IgG titres at 78 months after the onset of symptoms in convalescent individuals, consistent with the long-term maintenance of antibody levels by these cells (r=0.48, P=0.046). People who have had a mild case of COVID-19 are left with long-term antibody protection against future disease, according to a study from researchers at Washington University School of Medicine in St. Louis.
