Authors' recomendations: Evidence from swabs submitted from patients in the cohort presenting with influenza-like illness in general practice suggests that the introduction of influenza A (H1N1)v vaccine in Scotland during 2009 was associated with a high degree of protection against influenza A (H1N1)v. In addition, receipt of influenza A (H1N1)v vaccine was associated with a reduction in both admission for cardiac-related conditions and for the combined category of influenza, pneumonia, COPD and cardiac conditions. Policy-makers ought to be encouraged that the VE estimates obtained are comparable to those found for seasonal influenza. Additionally, as the first large-scale demonstration of effectiveness in a UK population, these interim results should help strengthen the evidence base for health-care practitioners involved in distributing influenza A (H1N1)v vaccine in other countries, now that the phased roll-out has been completed in the UK. Influenza A (H1N1)v immunisation in the primary health care setting is both effective and widely acceptable, as evidenced by high uptake rates, and should continue to be a mainstay of disease prevention for at-risk patients. Whether the reduced incidence of severe complications of influenza will persist or a reduction in mortality has occurred will only be apparent when data collected from later in 2010 are analysed.
