Description of intervention(s) / exposure
Open label, observational study of seasonal influenza vaccination in COPD patients and healthy age-matched control subjects.
COPD patients will be recruited over three (3) seasonal influenza vaccine years, with each year considered a separate cohort. Some patients will be repeat participants, however, they will be considered individual participants for separate years due to differences in age and physical parameters that occur in the course of one year. COPD patients will provide an initial single blood sample to be analysed of no more than 50ml, prior to receiving a single standard dose of inactivated and purified influenza vaccine in autumn of 2015, 2016, 2017. COPD patients will provide further single blood samples 24h post inoculation (p.i.) of no more 2.5ml, 7 and 28 days p.i. of no more than 40ml and 90 day p.i. of no more than 10ml.
COPD patients will be asked to attend three (3) mandatory study clinic visits, including administration of seasonal vaccine, with a additional 2 study clinic visits (days 7 and 90 p.i) being optional.

Statistical methods / analysis
Based on pilot data, a sample size of 36 COPD patients and 36 control subjects in each age strata (56-64 years, 65-74 years, and over 75 years) has a power of 90% to detect a difference between patients and controls in post-vaccination antibody titre at a significance level of 0.05. Thus a total of 108 COPD and 108 Control subjects will need to complete the study. On the assumption that 20% of participants will fail to attend one or more of the scheduled blood collections, we estimate that 135 COPD patients and 135 control subjects will need to be recruited.

Summary
Brief summary
Influenza infection is a frequent and important problem in chronic obstructive pulmonary disease (COPD). Influenza can have severe consequences in these patients, leading to acute exacerbations of COPD, pneumonia and respiratory failure. COPD patients are thus recognised as a group at particular risk of influenza, and current guidelines recommend yearly influenza vaccination. These recommendations are largely based on expert opinion and observational studies, with very few randomised controlled trials having been conducted in COPD. It has been suggested that people with COPD may have an aberrant immune response to influenza viruses, and as such, they may be less able to effectively mount an immune response to influenza vaccination. This study will examine influenza vaccination in people with COPD, and healthy age-matched controls, focussing on the factors that predict an effective antibody response to the vaccine (seroprotection), especially aspects of dendritic cell and T-cell function.
We will conduct an open-label observational study of seasonal influenza vaccine in 108 COPD patients and 108 healthy, age-matched control subjects. Subjects will receive a single dose of inactivated and purified split influenza vaccine in the autumn of 2015, 2016 and 2017. Primary outcomes of this study will be the proportion of vaccine recipients who achieve seroprotection or seroconversion.
