Keywords:

Introduction: The first vaccination in the Americas was a pivotal event in the history of preventive medicine and public health. Objective: To analyze the Royal Philanthropic Vaccine Expedition (1803–1806) from historical, medical, cultural, and bioethical perspectives.
Methods: A narrative literature review was conducted, drawing on historical and biomedical sources regarding smallpox, the development of vaccination by Edward Jenner, and the expedition led by Francisco Javier Balmis.
Discussion: The study examined the epidemiological impact of smallpox in the Americas, the strategies used to preserve and transport vaccine material, and the sociocultural and ethical factors involved in its implementation.
Conclusions: The analysis revealed that this process represented not only a momentous scientific advancement but also a phenomenon shaped by cultural tensions, social inequalities, and ethical dilemmas—an understanding of which offers relevant lessons for contemporary medicine.
