- Injection of snake antivenom against snake bite is an example of active immunisation
- If due to some reason B-and T-lymphocytes are damaged, the body will not produce antibodies against a pathogen
- Injection of dead/inactivated pathogens causes passive immunity
- Certain protozoans have been used to mass produces hepatitis B vaccine

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, ie, B-lymphocytes and T-lymphocytes. The B-lymphocytes produce an array (a range) of proteins in response to pathogens into our blood to fight with them. These proteins are called antibodies. The T-cells themselves do not secrete antibodies but help B-cells to produce them.
