Seasonal influenza vaccination coverage in France during two influenza seasons (2007 and 2008) and during a context of pandemic influenza A(H1N1) in 2009.

Abstract

OBJECTIVES

To measure the seasonal influenza vaccination coverage rate (VCR) in France in 2009, year of the A(H1N1) influenza pandemic, by age and target disease and compare it with the VCR for the 2007 and 2008 influenza seasons.

METHOD

At the beginning of each annual seasonal vaccination campaign, the National Health Insurance, covering 86% of the French population, sends free influenza vaccination vouchers to at-risk beneficiaries aged under 65 suffering from diverse chronic diseases and to all individuals aged 65 and over (around 11 million). Vaccination is estimated from refund claims registered in the National Health Insurance Information System.

RESULTS

The global VCR for the target population was 51% in 2007, 55.8% in 2008 and 56.9% in 2009. In 2009, the VCR for children under 10 years old was 24.3%, 28.1% in the 10-19 age range, 39.2% in the 20-64 age range and 63.3% for individuals aged 65 and over, of which 72.3% with a targeted chronic disease and 56.9% without. The inclusion of asthma as a target disease, lowered the global VCR for children under 10 years old (30.6% without asthma) but VCR increased proportionally with the number of annual refunds for drugs against asthma and chronic obstructive pulmonary disease. The 2009 vaccine uptake rates in target group children, adolescents, young adults and to a lesser extent the population aged 65 and over suffering from a chronic disease (particularly chronic respiratory disease), could have been positively impacted by the A(H1N1) influenza context.

CONCLUSION

The influenza VCR varies considerably according to age and target disease but globally remains inferior to the recommended 75% coverage rate. These results permit the detailed analysis of VCR distribution by disease and target group and highlights areas for reflection and action. Specific studies should be conducted in order to understand why the VCR is lower in certain target groups.
