INTRODUCTION: Since the late 1940s, mass vaccination programs in the USA have contributed to the significantly reduced morbidity and mortality of infectious diseases. To assist the evaluation of the benefits of mass vaccination programs, the number of individuals who would have su ered death or permanent disability in the USA, had mass vaccination never been implemented, was estimated for several infectious diseases. MATERIALS & METHODS The estimates accounted for mortality and morbidity trends observed for the infections prior to mass vaccination, adjustments of pre-vaccine estimates using data recorded after vaccine licensure, and the impact of advances in standard of living and health care (such as improved nutrition, sanitation, hygiene, and the treatment of disease). The estimates also considered populations with and without known factors leading to an elevated risk of permanent injury from infection. The estimates are based on data principally from reports of the CDC, complemented by reports from other federal entities such as the US Bureau of the Census and the US Public Health Service. Data recorded in scientific journals (e.g., JAMA, Pediatrics, JID, NEJM, and JCO) were used in cases when data from government sources were unavailable or incomplete. The estimates focused on the population the population <80 years of age because the life expectancy in the USA was 79 years. RESULTS Mass vaccination programs may prevent 20 million infections and 12,000 deaths and permanent disabilities annually among individuals <80 years of age. Individuals who have conditions or behaviors that would put them at higher risk of permanent injury from infectious diseases comprise 90% of all the estimated cases of prevented death and permanent disability. Although 9,000 of the estimated prevented deaths and disabilities were from liver cirrhosis and cancer, mass vaccination programs have not, at this point, shown empirical impacts on the prevalence of those conditions. The table below summarizes the results for the infections examined in this report. Mass vaccination programs targeting rotavirus, hepatitis A, influenza, meningococcal disease, and pneumococcal disease were each estimated to prevent fewer than 100 deaths among individuals <80 years of age.
