Maximising influenza vaccination awareness and uptake among older adults in Singapore.

Adults ≥65 are more susceptible to influenza infection and its associated complications. This paper critically reviews the literature, identifying the need for and priorities of a public health strategy to improve vaccination awareness and uptake among older adults. Four electronic databases were searched for peer-reviewed articles in English published between 2001 and 2016. Twelve studies were included. Three themes were identified on analysis: impact on healthcare services; barriers and motivators influencing influenza vaccination uptake; and health promotion interventions. Studies suggest vaccination may reduce the health-care costs of influenza-associated infection. Socioeconomic factors, information about vaccination and cultural beliefs may influence an individual's decision. Multicomponent interventions, such as home visits combined with reminders, support increased uptake. Interventions are identified that could be adopted at the community level in Singapore and other countries to improve influenza vaccination uptake among older adults.
