Question

Identify the wrong statement with reference to immunity:

• A. Active immunity is quick and gives full response
• B. Foetus receives some antibodies from mother, it is an example for passive immunity
• C. When exposed to antigen (living or dead) antibodies are produced in the host’s body. It is called 'active' immunity.
• D. When ready made antibodies are directly given, it is called 'passive' immunity.

Answer 1

The correct option is A Active immunity is quick and gives full response

Active immunity is slow and takes time to give its full effective response. Foetus receiving some antibodies from their mother, through the placenta during pregnancy is an example of passive immunity. Active immunity is the immunity in which when host is exposed to antigens (either living or dead), it stimulates the production of antibodies in response. In passive immunity, readymade antibodies are directly given to protect the body against foreign agents.
