What is the main objective of the National Immunization Program (NIP) in the Philippines?

The primary objective of the National Immunization Program (NIP) in the Philippines is to protect Filipinos from vaccine-preventable diseases. This initiative is essential for public health as it aims to reduce morbidity and mortality associated with diseases that can be prevented through vaccination, such as measles, poliomyelitis, and hepatitis.

By implementing a robust immunization schedule, the NIP seeks to create herd immunity within communities, thereby safeguarding not only those who are vaccinated but also those who are unable to receive vaccinations due to medical reasons. The focus on vaccinating children and other vulnerable populations reflects a commitment to improving overall health outcomes and preventing outbreaks of communicable diseases.

The other options do not align with the mission of the NIP. Increasing healthcare costs does not serve the public health intent of the program; promoting alternative medicine diverges from the established evidence-based practice of vaccination; and supporting only adult vaccination would neglect the priority of childhood vaccinations, where the burden of vaccine-preventable diseases is often greatest. Therefore, the answer highlighting the protection against vaccine-preventable diseases accurately reflects the NIP's core mission.
