**Core Concept**
Measles elimination requires high levels of vaccine coverage, especially in successive birth cohorts, to prevent the spread of the disease and ultimately eliminate it from a population. This concept is based on the principle of herd immunity, where a sufficient percentage of the population is immunized to prevent the spread of an infectious disease.

**Why the Correct Answer is Right**
High vaccine coverage in successive birth cohorts is crucial for measles elimination because it prevents the introduction and spread of the virus in the population. This is achieved by vaccinating a large enough proportion of the population to prevent outbreaks and, ultimately, to eliminate the virus from the population. The measles vaccine is highly effective, with a vaccine efficacy of around 93%, and its impact is amplified when a large percentage of the population is immunized.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the target level of vaccine coverage, making it an incomplete and vague answer.
**Option B:** This option is incorrect because it does not provide a clear target for vaccine coverage in successive birth cohorts, which is essential for measles elimination.
**Option C:** This option is incorrect because it does not specify the level of vaccine coverage required to achieve measles elimination, which is a critical factor in the success of the program.

**Clinical Pearl / High-Yield Fact**
To achieve measles elimination, it is essential to maintain high levels of vaccine coverage, especially in areas with low healthcare access and high population mobility. This requires a sustained effort from healthcare providers, policymakers, and the community to ensure that all individuals are vaccinated against measles.

**Correct Answer:** 95% (Correct Answer: 95% is generally accepted as the target level of vaccine coverage for measles elimination in successive birth cohorts.)
