When ready-made antibodies are directly given against foreign agents, it is called passive immunity.
Correct Answer:
Active immunity is very fast to give its full effective response.
Explanation:
Innate immunity is non-specific type of defence, that is present at the time of birth.When a host is exposed to antigens, which may be in the form of living or dead microbes or other proteins, antibodies are produced in the host body. This type of immunity is called active immunity. Active immunity is slow and takes time to give its full effective response.When ready-made antibodies are directly given to protect the body against foreign agents, it is called passive immunity. The foetus also receives some antibodies from their mother, through the placenta during pregnancy. These are some examples of passive immunity.
