Abstract:

This article discusses the immunization activities undertaken in the Region of the Americas over the last century, particularly those launched in the last quarter century, when the countries of the Americas accelerated their immunization-related activities. A century ago, in 1902, Walter Reed first identified that yellow fever was transmitted by a mosquito. The first yellow fever vaccine was developed in New York, by Max Tyler in 1937, and it was used in Brazil in the same year. Subsequently, there were several disease eradication efforts initiated in the Region of the Americas throughout the century. This is a chapter included in Vaccines. Preventing Disease and Protecting Health, a book that celebrates the ways in which vaccines have played a role in improving the health of the world's populations.
