• A. Chemotherapy
• B. Vaccination
• C. Radiation therapy
• D. Surgical intervention

Correct answer: B

Rationale: Vaccination is a preventive measure used in public health to protect against infectious diseases by stimulating the immune system to develop immunity without causing the disease.

2. Which of the following is an example of a live attenuated vaccine?

• A. Hepatitis B vaccine
• B. Inactivated polio vaccine
• C. Measles, Mumps, Rubella (MMR) vaccine
• D. Diphtheria, Tetanus, Pertussis (DPT) vaccine

Correct answer: C

Rationale: The Measles, Mumps, Rubella (MMR) vaccine is an example of a live attenuated vaccine because it contains weakened versions of the viruses that cause measles, mumps, and rubella. These weakened viruses can replicate in the body to stimulate an immune response without causing the diseases themselves.

3. Which vaccine leaves a permanent scar at the site of injection?

• A. BCG
• B. DPT
• C. Hepatitis B vaccine
• D. Measles vaccine

4. In the census of the Philippines in 1995, there were about 35,299,000 males and about 34,968,000 females. What is the sex ratio?

• A. 99.06:100
• B. 100.94:100
• C. 50.23%
• D. 49.76%

Correct answer: B

Rationale: The sex ratio is calculated as the number of males for every 100 females in the population. To find the sex ratio, divide the number of males by the number of females and multiply by 100. In this case, (35,299,000 / 34,968,000) * 100 ≈ 100.94:100. Therefore, the correct answer is B, indicating that there were approximately 100.94 males for every 100 females in the Philippines in 1995.

5. At what age is the first dose of the MMR vaccine typically administered to a child?

Correct answer: C

Rationale: The first dose of the MMR vaccine is typically administered to a child at 12 months of age to provide protection against measles, mumps, and rubella. Administering the vaccine at this age ensures that the child's immune system is developed enough to generate a protective response to the vaccine.
