  1. Seasonal influenza vaccination in the WHO European Regionpreliminary results WHO workshop on sentinel influenza surveillance, 16-17 November, 2011 Istanbul, Turkey Pernille Jorgensen |Influenza and other Respiratory Pathogens WHO Regional Office for Europe In partnership with the VENICE Collaboration and ECDC

  2. Background influenza vaccines • Influenza vaccines introduced 1940s • Vaccination is primary means of preventing influenza today • Excellent safety record • High efficacy:70-90% in healthy adults • …but lower in the elderly... • 60% in persons >60 years • 30-40% in persons >85 years

  3. Priority groups for influenza vaccination • Elderly • Health care workers • Pregnant women • Residents of institutions for older persons and the disabled • Individuals >6 months with underlying chronic medical conditions Reference: WHO/Europe recommendations on influenza vaccination during the 2011-2012 winter season www.euro.who.int/__data/assets/pdf_file/0008/152297/EURO_2011_2012_flu_vacc_rec.pdf

  4. First VENICE survey on seasonal influenza vaccination in WHO European Region

  5. Aims and objectives Aim • To assess progress toward the WHO goal of 75% influenza vaccine coverage in elderly by 2010 Specific objectives • Identify country specific vaccine recommendations • Describe influenza vaccine coverage in 2008/2009 and 2009/2010 • Describe influenza vaccination implementation • Provide a baseline from which to measure future improvements in seasonal influenza vaccine uptake

  6. Methods • Self-administered questionnaire to national vaccination focal points, 53 WHO Member States in August 2011

  7. Preliminary results • Response from 46/53 (87%)

  8. National influenza vaccination programmes • 43/46 (93%) countries had access to seasonal influenza vaccines in 2008/2009 season

  9. Seasonal influenza vaccine doses available relative to total population • Range from <1% to 23% • Note: Limited vaccine availability may reflect risk group vaccination policies

  10. National recommendationsfor vaccination seasonal influenza Clinical risk groups Elderly HCW hospital + outpatient Pregnancy

  11. National recommendationsclinical risk groups

  12. National recommendationsfor vaccination seasonal influenza Children

  13. Principal outlets for administration of seasonal influenza vaccine & cost Cost of single dose vial or prefilled syringe (€) Primary health care clinics are most important site for seasonal influenza vaccination in 90% of countries Median: 5.1 EUR

  14. Vaccine uptake in elderlyEU/EEA countries, 2008/2009 75% coverage target

  15. Influenza vaccination coverageClinical risk groups, 2008-2009 N=6

  16. Influenza vaccination coverage Health care workers, 2008-2009 N=9

  17. Seasonal influenza vaccination campaigns • 81% produced specific information for public and health professionals • 73% made use of media campaigns • 93% TV • 93% News paper adds • 87% Radio • 73% Posters

  18. Conclusions • Most countries in the Region have access to seasonal influenza vaccine • Similar recommendations for “traditional” risk groups in the Region • Only, 1 country reached WHO 2010 target of coverage >75% among elderly • Low coverage in health care workers • Cost of influenza vaccine very similar • Frequent use of media campaigns to promote influenza vaccination

  19. Key challenges • Limited vaccine uptake monitoring • Difficult to monitor progress • Difficult to monitor impact • Low vaccine uptake • Limited vaccine access in some countries

  21. Next steps -country plans • Change seasonal vaccine recommendations and include pregnant women and persons with morbid obesity • Prioritization of risk groups in settings with limited quantity of vaccines • Assessing cost-benefit of influenza vaccination programme in different settings • Evaluating vaccine uptake • Improve perception of influenza vaccines in the public
