ABSTRACT
Global coverage with three doses of the diphtheria, tetanus and pertussis vaccine (DTP3) increased from less than 5% in 1974 to 82% in 2009 due to worldwide focus on universal vaccination. Nonetheless, pertussis remains the fifth-leading cause of vaccine-preventable deaths. This study examines DTP3 vaccination from 1980 through 2009 in three countries within Latin America, Bolivia, Brazil and Mexico, selected for their distinct health care systems and vaccination strategies. Similar to global trends, these nations have achieved dramatic improvements in pertussis immunization. In Bolivia, immunization rates increased from 11% to 85%; in Brazil, rates increased from 37% to 97%; and in Mexico, the immunization rates increased from 44% to 72%. Pertussis infections have concomitantly decreased from 1980 to 2009. In Bolivia, cases decreased from 44.4 per 100,000 people to zero reported cases. In Brazil, the incidence decreased from 37.6 to 0.5 cases per 100,000. The incidence in Mexico decreased from 8.2 to 0.5 cases per 100,000. In order to increase vaccination rates further, health systems must continue to raise awareness about disease prevention, expand health surveillance systems, and improve access to health services.
