Answer 1

Hey Friend,

The answer is SERUM...

Serum is a clear, watery, and yellowish part of blood left behind when the erythrocytes, blood platelets and the blood protein fibrinogen have been removed from it by clotting. 
Serum, when injected in one's body, cures him and also gives protection against future attacks by such microorganisms.

Hope it helps!
