Question

Difference between active and passive immunity

Answer 1

The two main types of immunity are active and passive immunity.

Active immunity is the immune response to a pathogen. It relies on the body making antibodies, which take time to mount an attack against bacteria or viruses.

Passive immunity occurs when antibodies are introduced rather than made (e.g., from breast milk or antisera). The immune response occurs immediately.

Other types of immunity include specific and nonspecific defenses as well as innate and acquired immunity.

Answer 2

Answer:

Active immunity

• It is a type of acquired immunity in which the body produces its own antibodies against disease causing antigens.  
• It is a type of acquired immunity in which readymade antibodies are transferred from one individual to another.    
• It has a long lasting effect.
• It is slow. It takes time in producing antibodies and giving responses.  
• Injecting microbes through vaccination inside the body is an example of active immunity.  

Passive immunity  

• It is a type of acquired immunity in which readymade antibodies are transferred from one individual to another.    
• It does not have long lasting effect.
• It is fast. It provides immediate relief.
• Transfer of antibodies present in the mother’s milk to the infant is an example of passive immunity.
