Seasonal influenza vaccination
in the WHO European Region
preliminary 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
Slide 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
Slide 3
Priority groups for influenza vaccination
Individuals >6 months with underlying chronic
medical conditions
Elderly
Health care workers
Pregnant women
Residents of institutions
for older persons and
the disabled
Reference: WHO/Europe recommendations on influenza vaccination during the 2011-2012 winter season

Slide 4
First VENICE survey on seasonal
influenza vaccination in WHO
European Region
Slide 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
Slide 6
Methods
Self-administered questionnaire to national
vaccination focal points, 53 WHO Member States
in August 2011

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