But such speculation needs to be tested  we cant just rely on an educated guess. As such, it is sometimes harvested from people who have recovered from a disease and transfused into patients who are fighting it. However, data were still being collected in randomized controlled trials  the gold standard  to study the safety and effectiveness of the treatment.

Such purified antibodies are already used to treat patients with antibody deficiencies.
Gold study (abr) showed a higher proportion of patients with neural activity loss.
