What organization provides information about vaccinations needed and health risks abroad?

The organization that provides information about vaccinations needed and health risks associated with traveling abroad is the Centers for Disease Control and Prevention (CDC). The CDC offers detailed travel health notices, vaccination recommendations, and advice on preventing illnesses while traveling to various international destinations. It serves as a resource for travelers to understand the health risks they might face in different countries and what steps to take to protect their health.

While the World Health Organization (WHO) also plays a significant role in global health and disease prevention, its focus is broader and often centered around public health policies and response to health emergencies worldwide rather than delivering specific travel-related health guidance.
