- B. OPV
- C. Hepatitis B vaccine
- D. Measles vaccine
Correct answer: B

- B. Cold chain
- C. Potency of vaccines
- D. Health education
Correct answer: A
Rationale: Immunization coverage is the proportion of the target population that has been immunized. To control the occurrence of diseases effectively, it is crucial that a high percentage of the population is immunized. This not only protects individuals but also helps in achieving herd immunity, reducing the spread of diseases within the community. Therefore, ensuring high immunization coverage is a key strategy in disease prevention and control.
3. Which demographic tool may be used to describe the sex composition of the population?

Correct answer: D
Rationale: To describe the sex composition of the population, both the sex ratio and sex proportion can be utilized. The sex ratio provides a numerical comparison of the number of males to females in a population, while the sex proportion expresses the relative number or percentage of males and females in a given population. On the other hand, a population pyramid is a graphical representation that shows the age and sex distribution of a population. Therefore, any of these tools may be used to analyze and present the sex composition of a population.
