NEW DELHI: With a long road ahead for vaccines and drugs, scientists are now exploring age-old technique of passive antibody therapy as potential treatment for COVID-19, which has infected over 5 lakh people across the world and killed at least 24,000.
Antibodies are protein molecules released by the body when a foreign substance (like for instance, virus) enters the system.
These molecules bind to the foreign substance and neutralize it. Simply put, they are the weapon used by the immune system to fight new infections.
In case of COVID-19, over 1.22 lakh people, including a large young population, infected with the disease have recovered globally.
