There are two portion of BLOOD :
• CELLS – It contains RED BLOOD CELLS, WHITE BLOOD CELLS, PLATELETS
• PLASMA – When we remove cells from the blood the left over liquid portion is PLASMA . It contains water, salts ,enzyms, antibodies and other proteins. In our body 54% of blood is plasma.
THERAPY: When our body comes in contact with external PATHOGENS like Bacterias, Viruses , then our body automatically generates a defense system and our immune system produce some proteins to fight against infections , that proteins are called ANTIBODIES .
If an infected parasite body produces a sufficient antibodies then it recovers from the disease, which happened because of the pathogens entered in the body.
So, the idea behind the plasma therapy is that :
Take this immunity from the healthy person who has cure from the same disease and that antibodies can be transferred through blood to a person whose body can not make antibodies to fight against virus. So, in this therapy one’s blood is taken from a cured person and separates the plasma from the blood and screened whether that plasma has antibodies that neutralise the particular virus.
That plasma which have antibodies to fight against COVID-19 and that plasma is infused to the other CORONAVIRUS patients whose body cannot make antibiotics to fight against COVID-19 .
There is a difference between vaccine and therapy – Therapy provides temporary immunity whereas, Vaccine provides life time immunity.
THE INDIAN COUNCIL OF MEDICAL RESEARCH (ICMR) , recently gives permission to kerala to conduct the plasma therapy, and kerala is the first state of india who conducts plasma therapy .
Doctors are hoping,this method is beneficial until the other treatments arrive.
