Vaccination

Why it matters

• Serves as a primary public health intervention to reduce morbidity and mortality from communicable diseases.
• Facilitates the development of herd immunity, protecting vulnerable populations who cannot be vaccinated.
• Reduces the long-term economic burden on healthcare systems by preventing outbreaks and chronic complications.
• Supports global health security by limiting the transmission of pathogens across borders.

How it is asked

Focus on the mechanism of immune response, the role of vaccination in public health policy, challenges in vaccine distribution and logistics, and the ethical considerations regarding mandatory immunization versus individual autonomy.
