Abstract: The world has suffered immensely with outbreak of SARS-COV-2 in the end of 2019. Amidst this, some cases of recurrence of SARS-CoV-2 in COVID-19 recovered patients have come forward that seeks attention. In desperate times, before the advent of vaccines for this disease, the health care professionals inclined to an underestimated age-old therapy of antibody transfusion for emergency prophylaxis. The authors have explored various research papers and journals leading with relevant words in online database, independently studying to draw inference and finally converge the gathered information into a review paper. Possible reasons for reinfection incline towards falsely negative results mostly. However, people with comorbidities are

 at a higher risk of reinfection. Viral mutations can also be a cause of reinfection. The underestimated antibody therapy has helped in reducing the symptoms during infection and mitigated the viral replication showing good efficacy. The chances of recurrence are low after recovery. Standardisation of diagnostic tests seeks improvement before discharge from hospital. Post recovery isolation is encouraged. The early transfusion of high titre antibody has been of great help showing effectively low mortality rates.
