Factors that impede wider usage include:
• Public health strategy – vaccine policy
• Resource availability – vaccine supply
• Fiscal space – vaccine costs
• Health infrastructure – vaccine delivery and implementation
• Cultural perceptions – public perceptions

WHO position paper on seasonal influenza*
� Risk-based approach to vaccination:
– Elderly in long-term care facilities
– Elderly with chronic conditions
– Anybody >6 months with high risk conditions
– Elderly above a nationally defined age limit
