The MMR vaccine provides protection against all of the following diseases, except:
Appeared in: NORCET-11 Prelims
Explanation
- MMR vaccine protects against measles, mumps, and rubella only.
- Rickettsia is a bacterial group not covered by the MMR vaccine.
- Key differentiator: MMR covers only viral diseases, not bacterial ones like Rickettsia.
Why Other Options Were Wrong
- Option A: Measles is one of the three diseases specifically targeted by the MMR vaccine.
- Option B: Mumps is also included in the MMR vaccine, providing immunity against this viral infection.
- Option C: Rubella is the third disease in the MMR vaccine, also known as German measles.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Diseases covered by the MMR vaccine and exception identification as background academic context rather than a clinical decision trigger.
- Nurses must know which vaccines protect against which diseases to educate patients and ensure proper immunization.
- Misunderstanding vaccine coverage can lead to missed opportunities for disease prevention.
- What if? If a patient is at risk for Rickettsial diseases (e.g., due to tick exposure), they need different preventive measures, not the MMR vaccine.
How to Approach the Question
- Identify the diseases included in the MMR vaccine by recalling what MMR stands for.
- Recognize that Rickettsia is a bacterial group, not a virus, and not included in MMR.
- Use process of elimination for exception-based questions: eliminate options that are clearly included in the vaccine.
- For similar questions, always check if the disease is viral or bacterial and if it matches the vaccine's target.
Concept Tested & Keywords
