Childhood Vaccination Implications for Global and Domestic Public Health

The role of vaccination in the control and prevention of endemic and emerging diseases cannot be overemphasized. Induction of host protective immunity may be the most powerful tool and effective strategy in preventing the spread of potentially fatal disease and emerging illnesses, in particular in susceptible immunologically naive hosts. The strategy for vaccination programs is engrained in population studies recognizing benefit for the health and economic welfare of at -risk indigenous populations. Worldwide collaboration is a necessary aspect of vaccine -preventable diseases recognizing that even a small number of wild -type cases of an eradicated disease in one region presents opportunities for re-emergence of the disease in geographically remote areas.
