Randomized Controlled Trial Clinical Trial
Adverse effects associated with influenza vaccination in patients with COPD: a randomized controlled study.
The aim of this study was to assess the frequency and type of adverse reactions following influenza vaccination and its effects on lung function, dyspnoeic symptoms, exercise capacity, and clinical acute respiratory illness (ARI) in patients with COPD, and the relationship of these adverse effects to the degree of airflow obstruction. ⋯ Influenza vaccination is associated with minimal local adverse reactions in patients with COPD. Vaccination does not cause systemic adverse reactions, induce clinical exacerbations or adversely affect lung function, dyspnoeic symptoms and exercise capacity in patients with COPD, regardless of the severity of airflow obstruction.
