Question

Passive immunity is provided by readymade antibodies.

• A. True
• B. False

Answer 1

The correct option is A

It can also be induced artificially when high levels of antibodies specific to a pathogen or toxin are transferred to non-immune persons (examples: immunoglobulin therapy or antiserum therapy).
