Viral infections including infl uenza, respiratory syncytial virus (RSV), and many other viruses are important causes of exacerbations, excess morbidity and mortality in COPD (Wedzicha 2004; Wilkinson et al 2006) . Considering the infl uence of different respiratory viruses in stable COPD and the important role of viral infections in exacerbations, vaccination is a potentially effective way to reduce morbidity and mortality caused by exacerbations. In a randomized clinical trial, Wongsurakiat and colleagues (2004) demonstrated that infl uenza vaccination is highly effective in the prevention of acute respiratory illness related to infl uenza virus infection, regardless of severity of COPD, comorbid diseases, age, gender, or smoking status.	./cache/cord-343607-yu5n9eur.txt	./txt/cord-343607-yu5n9eur.txt
