Question

Active immunity and passive immunity.​

Answer 1

Answer:

Active immunity occurs when our own immune system is responsible for protecting us from a pathogen. Passive immunity occurs when we are protected from a pathogen by immunity gained from someone else.

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.
