P2. Immunisations

P2.1 Influenza immunisation

In people aged 65 years and older, annual influenza immunisation may lower the risk of influenza and probably lowers the risk of influenza-like illness (Demicheli 2018). A Cochrane systematic review has shown that in people with COPD, inactivated influenza vaccine reduced the total number of exacerbations per vaccinated person, compared to placebo (mean difference -0.37, 95% CI -0.64 to -0.11, n=180 patients; rated as low quality evidence due to only 2 RCTs) (Kopsaftis 2018) [evidence level I]. There was no change in rates of hospital admission or mortality. Adverse effects are mild, local, transient and self-limiting and include sore arm, mild fever and arthralgia.
