TYPE-SPECIFIC PNEUMOCOCCAL RESPIRATORY-DISEASE IN ELDERLY AND CHRONICALLY ILL

Abstract
Type-specific pneumococcal respiratory disease was studied in a chronic-disease hospital during a 27-mo. period. Isolates from 50 patients with pneumonia and from 24 patients with chronic bronchitis were available for typing. Vaccine types were isolated from 74% of patients with pneumonia and from 42% of patients with chronic bronchitis. Pneumococcal types isolated from 5 of 8 patients with bacteremia and from 6 of 9 patients who died were also included in the vaccine. Closed populations of elderly and chronically ill patients would possibly benefit from vaccination in an attempt to control pneumococcal pneumonia. Less clear is the potential role of vaccination in patients with chronic bronchitis.
