The Singapore Government has announced the “Healthier SG Initiative”, a new healthcare reform plan. Its focus and effort is to promote healthy living and to tackle the challenges of an ageing population. As part of this initiative, free vaccinations against influenza and pneumococcus will be offered to the elderly. Vaccination is a powerful public health tool in the prevention of infectious diseases. The implementation of National Childhood Immunisation Programme in many countries has led to improvement in child health and mortality from preventable infectious diseases. Many who have benefitted from such programmes are now adults and experiencing waning immunity. The ageing adult population is also vulnerable to many infectious disease threats due to immunosenescence. There is much that we can do to bolster take up rates for adult immunisation. We need to understand the patterns of vaccine preventable infections in this population, their needs, barriers to immunisation, access and further develop ways to scale up adult vaccination programmes.
