Immunosenescence and vaccination in nursing home residents

Protective effect of vaccination against induced influenza A. For studies assessing laboratory-confirmed outcomes, estimates of vaccine efficacy may also be affected be the sensitivity of the diagnostic tests used. There are many age-related alterations in the signalling cascade of T cells, including calcium metabolism, tyrosine kinase phosphorylation, and protein kinase C translocation to the membrane.

Symptoms of immediate hypersensitivity range from urticaria hives to angioedema and anaphylaxis. Because of influenza vaccine shortage, a plan was enacted to distribute the limited vaccine stock to these groups first.

Aging is associated with decreased oxidative phosphorylation coupling efficiency and increased superoxide production. This last recommendation will be published in the recommendations of the ACIP on the prevention and control of influenza.

On the basis of these observations, we believe efforts should be concentrated on achieving high vaccination coverage in long-term care facilities coupled with a systematic assessment of the effect of such a policy.

The decision has to be taken in February in order to give the manufacturers sufficient time to gear up and produce the vaccine.

Annual influenza vaccination is the primary means of preventing influenza and its complications. The prevalence of infections such as respiratory, skin and soft-tissue, and urinary tract infections in nursing homes ranges from 1.

Numerous studies have shown that influenza vaccination works -- including to help protect the elderly from serious illness and hospitalizations -- but the degree to which it works varies from year to year and can be difficult to measure.

Allergic reactions might be caused by the vaccine antigen, residual animal protein, antimicrobial agents, preservatives, stabilizers, or other vaccine components This vaccination strategy, based on direct protection of those most at risk, has not been very effective in reducing influenza morbidity and mortality.

The magnitude of this effect differs among adults and children. However, during the —11 season, when all three vaccine virus strains appeared antigenically similar to circulating strains, vaccine effectiveness among children was similar to that observed for those of all ages in a large multisite observational study that used RT-PCR—confirmed medically attended influenza virus infections as the outcome all ages: Administration of —08 seasonal vaccine to adults boosted T-cell responses to both seasonal and pandemic H1N1 HA 93 ; this effect was significantly greater for LAIV.

The proportion of circulating influenza B viruses that are of the lineage represented in the vaccine has varied.

An open-label, nonrandomized, community-based influenza vaccine trial conducted among 7, children aged 5 through 18 years during an influenza season when circulating H3N2 strains were poorly matched with strains contained in the vaccine also indicated that LAIV, but not IIV, was effective against antigenically drifted H3N2 viruses.

These findings indicated that ORS symptoms following use of the reformulated vaccine were mild, resolved within 24 hours, and might not typically be of sufficient concern to cause vaccine recipients to seek medical care Healthy Children A randomized, double-blind, placebo-controlled trial among 1, healthy children aged 15 through 71 months assessed the efficacy of LAIV against culture-confirmed influenza during two seasons.

Immunosenescence: implications for vaccination programs in the elderly

The vast range of maximum lifespan differences between species provides convincing evidence that longevity is genetically influenced.

An elephant lives about 10−20 times longer than a mouse, yet both animals have roughly the same number of lifetime heartbeats — the elephant at 30 per minute and the mouse at per minute.
