Low Immunity Response in the Elderly

Aging is related to a number of changes in the immunity function, mainly the reducing of Cell Mediated Immunity (CMI). The immunocompetence of elderly worsen with age including the rate of immune respons against infection. It means that older people have a high risk of getting diseases such as infection, cancer, cardiovascular, autoimmune disorder, or other chronic diseases. All of these diseases occured in elderly due to the immunoglobulin production decrease. Thus, vaccination given to elderly often might not be effective against diseases. Older people who commonly suffer from a decrease of macro and micronutrients will have a low function and response of the immune system. Therefore, malnutrition cases in elderly should have early specific attention including consideration in given vaccination for preventing diseases. Infectious diseases mostly suffered by older people can be prevented or reduced through improving nutrition efforts because the immune system will be improved. If the immune function of the elderly can be improved, the individual quality of life increases and the health cost can be suppressed.&nbsp
