FDA approves Convalescent Plasma Treatment for seriously ill COVID-19 patients

The Food and Drug Administration of the United States has approved the use of Convalescent plasma collected from patients recovered from COVID-19 to treat seriously ill COVID-19 patients. The idea of the method is to inject plasma with antibodies into critically ill patients for them to gain immunity against the virus.


The Convalescent plasma treatment had earlier been studied during the outbreaks of 2003 SARS-CoV-1 epidemic, 2009-10 H1N1 influenza virus and 2012 MERS-CoV epidemic.

The treatment is mere collection of plasma from a COVID-19 recovered patient and inject them into a critically ill patient of COVID-19

What is Plasma?

Plasma is the major part of the blood. Apart from RBC, WBC and platelets in the blood, all the other fluid content is referred as Plasma. It makes up more than 55% of blood in human body. When separated from blood, it becomes light yellow liquid. This is because, blood is red in color due to the RBCs.

The main role of plasma is to carry hormones, nutrients and proteins to different parts of the body.

The DRDO (Defence Research Development Organization) has been tracking the spread of the COVID-19 virus since it began to spread in China. Now, the organization has developed four items to help India in its “War against Corona”.


The DRDO has developed hand sanitizer, ventilators, five-layer masks and body suits.

DRDO is to make 20,000 to 30,000 litres of hand sanitizers per day. The cost of the sanitizers is less than Rs 120 per litre

N99 masks

DRDO has developed 5-layer N99 masks. Among the five layers, 2 layers are made of nano mesh. The organization is to manufacture 10,000 such masks a day. The cost of the mask is Rs 70 per piece


The Society for Biomedical Technology programme, operating under DRDO has been modified to fulfil the current needs. The programme will now be deployed to manufacture ventilators. Around 5,000 ventilators are to be produced in the first month. It is then to gradually be increased to 10,000 in the subsequent month.
