The societal value of universal childhood vaccination.

Availability of new vaccines preventing infectious diseases in healthy children populations is increasing worldwide. In Canada, despite the current recommendation of the National Advisory Committee on Immunization to include recent vaccines in routine schedule, only a few provinces have incorporated some of the newer vaccines in routine vaccination programs. A review was undertaken of economic evaluations of childhood vaccination strategies performed from the societal point of view in industrialized countries, to gain perspective on their global benefits. The general trend supports most universal vaccination programs as cost-saving or cost-effective for society. Comparison of vaccination programs with other health care interventions indicates that vaccines are often one of society's best healthcare investments. Current data suggest that the Canadian society would benefit from a more complete immunization program.
