What is the World Health Organization (WHO)?

The World Health Organization (WHO) is a specialized agency of the United Nations that is responsible for coordinating international public health efforts. It was established in 1948 and plays a crucial role in global health governance by providing leadership on health matters, shaping the health research agenda, setting norms and standards, and articulating evidence-based policy options.

As a specialized agency, its main objectives include combating infectious diseases, managing global health crises, improving maternal and child health, and addressing health inequities among nations. By working with countries and numerous partners, WHO also aims to ensure that all people have access to essential health services and can live healthier lives.

While the other options present different types of organizations or roles in health, they do not accurately describe the WHO's unique position as a UN agency focused on global health policy and implementation. The WHO’s scope and authority in public health initiatives worldwide distinguishes it clearly from non-governmental organizations, insurance providers, or charitable entities focused on vaccination.
