Immunosenescence and vaccination in nursing home residents

Lipids may also have important immunomodulatory effects, especially polyunsaturated fatty acids, which regulate the inflammatory process and response [ 21 ].

Following the primary response to T cell-dependent antigens, antigen-specific B and T cell numbers decline. IgA antibodies are particularly effective at binding and neutralizing viruses; therefore, mucosal vaccinations should be particularly protective against respiratory infections such as influenza.

Influenza Vaccine Linked To Less Hospitalizations Among Elderly

It is imperative that we expand our understanding of the biological and molecular mechanisms underlying immunosenescence in order to provide older adults with the many years of healthy, independent living that they deserve. Risk models that account for these environmental factors, composite comorbidity measures [ 2526 ], and specific measures of immune function [ 29—31 ] may be of value.

Nutritional interventions have been demonstrated to increase vaccine responses in older adults and experimental animals. One such disease is influenza, which affects the whole population, but the highest rates of complications and mortality are observed in the elderly 65 years old and aboveespecially in those who have one or more comorbidities like diabetes, hypertension and others.

Activation of APCs is required to initiate production of pro-inflammatory cytokines that upregulate homing receptors, which are required for the DC to migrate to the draining lymph node and present antigens to T cells. Serum levels of IL-6 were measured before and 1 and 6 months after immunization.

In contrast, immune responses to purified antigens ie, protein, polysaccharide, glycoconjugate, and inactivated microbes are more fleeting as they are rapidly cleared from the vaccination site. Age-associated changes in leukocyte phenotype and function impair primary vaccine responses and weaken long-lasting memory responses.

Age-associated inflammation seems to correlate with poor health in general, as higher than average levels of age-associated inflammation correlate with the development of chronic inflammatory disease, frailty, and general ill health. As we age, our bodies undergo complex changes that, among other things, progressively weaken our ability to respond to infections and develop immunity this is called immunosenescence.

Selective vaccination of children, adolescents, and healthcare workers HCWs reduces transmission of infections and protects unimmunized and immunocompromised individuals, such as the elderly, through herd immunity. Outbreaks of several infectious diseases, including the common cold, norovirus, and C.

T cell-mediated responses act to directly or indirectly kill infected cells. Lower respiratory tract infection, such as pneumonia and bronchitis, is the leading cause of admission to the hospital from infectious diseases and deaths among older adults, with influenza as the most important viral infection clinically.

Toll-like receptor—mediated mechanisms appear to be most vulnerable to subclinical vitamin D deficiency [ 20 ]. Vaccination is the most effective and least costly preventative measure in our arsenal; however, vaccines that are effective in children and young adults are often ineffective in older adults.

Ginde become a leading investigator of interventions to improve immunosenescence and reduce the burden of infection in older adults. Conversely, a robust vaccine response is a predictor of immune competence and good health.Menu of State Long-Term Care Facility Influenza Vaccination Laws.
