Influenza and pneumococcal pneumonia immunization. Protecting our high risk population.

Pneumonia and influenza (P & I) constitute Florida's sixth leading cause of death. The P & I death rate in 1987, 10.5 per 100,000, was the highest since 1978. Major target groups for one or both vaccines used in prevention, as recommended by the Immunization Practices Advisory Committee (ACIP), include persons with chronic diseases of the heart or lungs, residents of nursing homes and other chronic care facilities, and persons aged 65 and older. Despite well-defined recommendations, vaccine coverage rates in Florida are as low as 30% in persons greater than or equal to 65 years of age. Knowledge and attitude surveys demonstrate that low coverage among various population groups may be due largely to insufficient awareness and/or negative attitudes regarding pneumococcal and influenza vaccines. Conversely, recommendations by physicians and other health care providers are strongly associated with receiving either vaccine. If the incidence of P & I is to decrease substantively in Florida, much wider use of the vaccines must occur. Because so many high-risk patients depend on private physicians for health care, their role is critical to the success of Florida public health strategies to reverse P & I trends.
