Vaccination programs for children have a proven track record. Few of us can remember epidemics of polio, measles, and other often fatal diseases. The overwhelming majority of young children receive the CDC recommended immunizations. However, the adult population often remains under-immunized. This may occur because many adults do not know that they would benefit from vaccines. While the adult vaccine schedule does not have as many immunizations as the child schedule, there are several vaccines that adults can benefit from to optimize their health.
