Explanation

The pertussis component of the original DPT vaccine was a whole-cell (wP) preparation, which was responsible for a higher incidence of adverse effects.
Common side effects attributed to the whole-cell pertussis component include high fever, prolonged crying, and significant local reactions like pain and swelling.
Due to this higher reactogenicity, an acellular pertussis (aP) component was developed, leading to the DTaP vaccine, which has a better safety profile and is now preferred in many immunization programs.
The terms 'removed' or 'replaced' refer to this shift from the whole-cell (DTwP) to the acellular (DTaP) formulation to minimize side effects.

Option A: The tetanus component is a toxoid, not a whole-cell vaccine. It is generally well-tolerated and has not been removed or replaced due to side effects.
Option B: The diphtheria component is also a toxoid with a good safety profile. It is an essential part of the vaccine and was not the cause of the frequent side effects.
Option D: This is incorrect because only the pertussis component was modified due to its higher rate of side effects. The diphtheria and tetanus components remain standard.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Reactogenicity of DPT vaccine components as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in educating parents about the benefits and risks of vaccination. Understanding the difference between DTwP and DTaP allows nurses to address concerns about side effects accurately, which can improve vaccine acceptance and compliance.
Accurate assessment for contraindications to the pertussis vaccine is a key nursing responsibility. A history of encephalopathy within 7 days of a previous dose is an absolute contraindication, and the nurse must ensure the child receives the DT vaccine instead.
Nurses must be able to provide appropriate advice for managing common post-vaccination side effects, such as fever and local pain, and to recognize and report severe adverse events following immunization (AEFI).

How to Approach the Question

First, identify the core of the question, which is asking about a specific component of the DPT vaccine that was changed due to side effects.
Recall the three components of DPT: Diphtheria, Pertussis, and Tetanus.
Access your knowledge about the history and evolution of vaccines. The question implies a change was made over time.
Consider the nature of each component. Diphtheria and Tetanus are toxoids. Pertussis has existed in two main forms: whole-cell (wP) and acellular (aP).
Recognize that the whole-cell version of the pertussis vaccine was known to be more 'reactogenic' (causing more reactions) than the acellular version.
Conclude that 'Pertussis' is the component that was modified to reduce side effects, leading to the development of DTaP from DTwP.
