The principle of plasma therapy can be used for prophylaxis and treatment purpose. In view of non-availability of suitable vaccine for prevention or no established definitive therapy for SARS-CoV-2, plasma therapy is gaining importance in a current pandemic as one of the treatment options for the treatment of COVID-19.

In this mini review, an attempt has been made to review positive aspects, negative aspects and various limitations of the CP therapy for COVID-19 cases. The results of various studies show that CP therapy may be thought of one of the alternatives but while considering it as a therapeutic approach, in light of beneficial effects, the negative aspects and limitations are to be taken into consideration before its administration as a therapeutic agent.
