Prevention of influenza in the elderly

A gradual evolution has occurred in the development of influenza vaccines to their present highly purified state. Although studies are limited and vaccines are far from perfect, influenza vaccines should be used in the geriatric age group. Chemoprophylaxis is currently available against influenza A; however, studies should be made of its safety and efficacy in the elderly. Because of the severe consequences of influenza in aged persons, there is need for continued evaluation of vaccines, improved delivery, improved education, and new strategies for the prevention of influenza in the elderly.
