Abstract
Suboptimal vaccination coverage among individuals with chronic diseases increases the risk of preventable infections and related complications. Therefore, it is of interest to evaluate patient knowledge and vaccination practices and compared self-reported status with documented immunization records among 240 adults with chronic illness. Awareness of recommended vaccines varied widely, with 70% recognizing the COVID-19 booster but only 35% aware of pneumococcal vaccination. Documented coverage for pneumococcal and Tdap vaccines was 20.0% and 13.3%, respectively and discrepancies were observed between self-report and verified records. Thus, higher awareness and provider counselling were associated with improved documented vaccine uptake, highlighting persistent gaps in education and record verification.
