Factors influencing influenza and pneumococcal immunization rates of COPD patients in Bolu, Turkey

The aim of this study was finding out the rates of pneumococcal and influenza vaccination, the factors influencing vaccination, and non-vaccination in COPD patients. The study was conducted with 104 COPD patients diagnosed by a pulmonologist. The diagnosis was made according to the GOLD 2019 document via an FEV1/FVC ratio below 70%.

The study revealed a significant association between COPD levels and the awareness of the necessity of annual influenza vaccination (p=0.019).
