Ageing in the 21st Century

• Reductions of mortality in all ages have added extra years of life to individuals globally

• Increasing life spans likely continue, but gains may be offset unless accompanied by increasing good health

• Ageing individuals and societies demand a comprehensive, systematic methodology to achieve longer/healthier lives

• Such programs must and will include vaccines for the elderly

Complex Barriers to Adult Vaccination • Some vaccines are universally recommended for adults, while others

are recommended for certain age groups, targeted to individuals with specific risk factors or targeted to particular combinations of age and risk factors

Low level of patient awareness

Lack of available public health information

Lack of adult disease and vaccine surveillance

Lack of medical/scientific recommendation

Low level of government support for adult prevention and vaccines

Lack of reimbursement or willingness to vaccinate adults

Lack of adult vaccine administration settings/schedules

Low level of healthcare provider awareness of vaccine benefits
