Final answer:
Immunization is contraindicated in the presence of a history of anaphylactic reaction to a previous vaccine.
Step-by-step explanation:
The presence of a history of anaphylactic reaction to a previous vaccine is a contraindication to receiving an immunization. An anaphylactic reaction is a severe allergic reaction that can be life-threatening and is characterized by symptoms such as difficulty breathing, hives, and swelling. Administering an immunization to an individual with a history of anaphylaxis can potentially trigger a similar reaction, so it is important to avoid immunization in such cases.
