Recently published findings on convalescent plasma therapy on Covid-19 patients have triggered a debate over its efficacy. 

About

What is plasma therapy?

• Plasma is the liquid part of the blood. Convalescent plasma, extracted from the blood of patients recovering from an infection, is a source of antibodies against the infection.
• The therapy involves using their plasma to help others recover.
• For Covid-19, this has been one of the treatment options. The donor would have to be a documented case of Covid-19 and healthy for 28 days since the last symptoms.

What has been found in the trials?

The country’s largest such trial, known by the acronym PLACID has found the following:

• Convalescent plasma was ineffectivein arresting Covid-19
• While use of convalescent plasma seemed to improve resolution of shortness of breath and fatigue in patients with moderate Covid-19, this did not translate into a reduction in 28-day mortality or progression to severe disease.
