Improving the health of Oklahomans through clinical prevention, Part III: Immunizations and chemoprophylaxis.

Vaccines are one of the greatest achievements of biomedical science and public health and are clearly one of the most effective tools of clinical prevention. Diseases that once caused significant morbidity and mortality in Americans--particularly children--have been virtually eliminated from the population through effective immunization programs. But until these diseases have been eradicated globally we must continue to maintain high immunization levels to prevent their return; a 90% coverage rate has been set as the national goal for recommended vaccines in preschool age children. In Oklahoma we have only achieved that goal for two vaccines (measles and polio) and for the last several years we have ranked near the bottom in vaccine coverage rates compared to other states. Although achieving high vaccination rates in children involves numerous partners, private physicians must play a major role in that effort since they are the primary vaccine providers in the state. Physicians should also be alert to the vaccine needs of their adolescent and adult patients, particularly for pneumococcal disease, influenza, hepatitis A and B, and tetanus. This article describes current vaccination levels in Oklahoma children and adults for several routine and newly recommended vaccines and discusses the role of private physicians in maintaining and improving immunization coverage.
