ABSTRACT
The proportion of the elderly in the population has been steadily increasing globally. In Singapore, it is estimated that a quarter of the population will be older than 65 years in 2030. The elderly are more susceptible to infections and once acquired, the infections are often more severe. Effective vaccination has been the most efficient interventional strategy to reduce the morbidity and mortality of infections in the young and greater attention should be paid to the use of vaccinations in the elderly.
