The severe respiratory infections in the current pandemic coronavirus disease-19 (COVID-19) have influenced more or less every human life. The first person to get infected with this virus was reported in the capital of Hubei province (Wuhan), China, in late December 2019. Since the disease has been declared a pandemic, research scholars and experts have been manufacturing new vaccines or targeted therapies to curb the spread of SARS-CoV-2. However, only limited options have emerged so far, which yet require complete scientific validation by long-term data collection regarding safety and efficacy. In the wake of the recent emerging wave of the pandemic viz omicron variant, changing facets of the viral genome and dearth of preventative and therapeutic possibilities for the management of COVID-19, the usage of Convalescent Plasma Therapy (CPT) may be looked at as a potentially viable option of treatment in the existing situation. Earlier, immune plasma has been used with success in the management of H1N1 influenza virus, MERS-CoV, and SARS-CoV-1 epidemics. In the present unpredictable situation created by the COVID-19 pandemic, the CPT is used with a positive outcome amongst many infected individuals in different parts of the world with acceptable efficacy. This article aimed to present an up-to-date evaluation of existing literature on the efficacy of convalescent plasma as a potential therapy, its safety and effectiveness and the challenges in treating COVID-19.
