Question

Passive immunotherapy is used when:________.A. the attenuated live vaccine is too difficult to produce B. the pathogen does not produce a toxin C. the microorganism can be genetically manipulated D. protection against a recent infection or disease is needed immediately E. a representative antigen for the microbe cannot be isolated

Answer 1

Answer: D. protection against a recent infection or disease is needed immediately

Explanation:

Passive immunisation is used when there is a high risk of infection and there is insufficient time for the body to build its own immune response or to mitigate the effects of active or immunosuppressive diseases.

Passive immunisation may be offered when people are unable to synthesise antibodies and when they have been exposed to a disease to which they have no protection. example of passive immunotherapy include monoclonal antibodies (MABs) or magic bullets which targets cancerous cells.

Hence, the correct option is D.
