influenza vaccine for elderly high dose
a high-dose, inactivated, split-virus influenza vaccine (IIV3-HD Fluzone High-Dose vaccine, Sanofi Pasteur) was developed.4 Should primary care practitioners routinely choose this vaccine for their elderly patients? Overall, 2015/16 estimates against hospitalised influenza in elderly people were moderate against influenza ADosage and schedule. Children not in a clinical risk group only require one dose of the vaccine.They may not make a full antibody response, so protection may not be as high as for Study data also indicated that the high-dose vaccine may provide clinical benefit for the prevention of hospitalizations, pneumonia, cardio-respiratory conditions, non-routine medical visits, and medication use.About 76 percent of this community of older adults are vaccinated for influenza each year." Elderly residents vaccinated with Fluzone High-Dose had hospitalization reductions of: 30 during H3N2-dominated seasons (P .006). Efficacy and immunogenicity of high-dose influenza vaccine in older adults by age, comorbidities, and frailty. High-Dose vs Standard-Dose In a randomized trial in 31,989 adults 65 years old, the high-dose vaccine (Fluzone High-Dose), which contains fourDo antibody responses to the influenza vaccine persist year-round in the elderly? A systematic review and meta-analysis. Vaccine 2017 35:212. The high dosage vaccine induced a higher frequency of serum antibody increases (> 4-fold) in both hemagglutination-inhibiting (HAI) and neutralization testsThese increased immune responses should provide increased protection against influenza in the elderly.

We dont yet have data to prove that the increase in antibody titers will result in fewer clinical influenza illnesses and complications, but it seems logical that it would. Influenza affects the whole population but the highest rates of complications and mortality are observed in the elderly.Just under half of the homes, administered the high-dose vaccine while the other provided a standard dose. The high dosage vaccine induced a higher frequency of serum antibody increases (4-fold) in both hemagglutination-inhibiting (HAI) and neutralization tests for all three vaccine viruses in theThese increased immune responses should provide increased protection against influenza in the elderly. High doses of challenge virus ( 105 ID50 or a lethal dose if known) are preferable. Important endpoints include The elderly and frail population should be an essential part of the post-marketing monitoring program envisaged. 7.2. Seasonal influenza vaccines. Keywords: influenza vaccination, vaccine immunogenicity, HI antibody titers, CHMP criteria, elderly institutionalized people.Advances in the vaccination of the elderly against influenza: role of a high-dose vaccine. Fluzone High-Dose vaccine should not be given to anyone with a severe allergic reaction (eg, anaphylaxis) to any vaccine component, including eggs, egg products, or to a4. Goodwin K, Viboud C, Simonsen L. Antibody response to influenza vaccination in the elderly: a quantitative review. The high-dose version of the trivalent inactivated influenza vaccine induced higher antibody responses and provided significantly improvedThis trial was designed to demonstrate those benefits by comparing its efficacy against that of the standard- dose vaccine (Fluzone) in the elderly. Abstract. On 23 December 2009, the US FDA approved Fluzone High Dose, a high-dose formulation of the trivalent inactivated influenza vaccine, for prevention of influenza in people 65 years of age and older. The authors concluded that improved immunogenicity of high-dose influenza vaccine among elderly persons should lead to enhanced protection against naturally occurring influenza. WASHINGTON U.S. health officials approved on Wednesday a high-dose influenza vaccine made by Sanofi-Aventis DA (SASY.PA) for people age 65 and older. [efoods]The vaccine uses a higher dose to produce a stronger immune response and better protect the elderly against seasonal flu, the The high dosage vaccine contained eight times as much NA activity as the standard vaccine and induced a significantly higher frequency of antibody responses and higher meanCorrelates of Protection against Influenza in the Elderly: Results from an Influenza Vaccine Efficacy Trial.

High-dose trivalent influenza vaccine compared to standard dose vaccine in elderly adults: safety, immunogenicity and relative efficacy during the 20092010 season. To improve vaccine efficacy in the elderly, a high dose formulation of the commonly used trivalent inactivated influenza vaccine (IIV) was tested in a large-scale Phase 3 clinical trial dubbed FIM12. Healthy ambulatory elderly were immunized with increasing doses of the 1984-1985 influenza vaccine formulation. Two types of vaccines, split-product vaccine (SPV) and whole virus vaccine (WVV), were used. High-dose trivalent influenza vaccine was developed to improve antibody responses to influenza vaccine in the elderly and hence potentially impact favorably on influenza-associated morbidity and mortality in this population. The U.S. Advisory Committee on Immunization Practices last week heard a report about the high-dose influenza vaccine that was recently approved for people 65 and older but voiced no preference for its use in that age group Influenza and pulmonary-related hospitalizations were lower in elderly patients who received the high-dose trivalent influenza vaccine.

Comparative effectiveness of high-dose versus standard-dose influenza vaccination The high-dose vaccine (1.30 outcomes per 10,000 person-weeks) was 22 more effective than the standard- dose vaccine (1.01 outcomes per 10,000 person-weeks) forPolicy makers should consider this new information in their recommendations for influenza vaccinations in the elderly. "Influenza can be especially severe for the most vulnerable populations, including the elderlyDuring the 2016-2017 season, about 60 percent of adults 65 years of age and older who were vaccinated in the United States received Fluzone High-Dose vaccine, helping to protect this vulnerable population. Background: High-dose trivalent influenza vaccine was developed to improve antibody responses to influenza vaccine in the elderly and hence potentially impact favorably on influenza-associated morbidity and mortality in this population. Recently, a research team from the University of Pittsburgh School of Medicine released the results of a study which compared the use of high dose influenza vaccine with regular flu shots in elderly patients confined to long term care facilities. SAN DIEGO — Results from a large, randomized controlled trial suggested high-dose influenza vaccination reduced hospitalizations among nursing home residents. As people get older, their response to vaccines goes down, Stefan Gravenstein, MD, MPH There is a high-dose flu vaccine specifically formulated to provide a stronger immune response. Available evidence indicates that vaccinating the elderly with the high-dose vaccine leads to a"Safety and immunogenicity of a high dosage trivalent influenza vaccine among elderly subjects". In comparison to the standard vaccine dose, the high-dose flu shot was well-tolerated in elderly adults, induced stronger immune responses and was better at preventing influenza infections than the standard-dose vaccine. Despite high vaccination rates, the elderly disproportionately bear the burden of seasonal influenza morbidity and mortality.High Dose Seasonal Influenza Vaccine vs. Standard Formulation. To improve vaccine efficacy in the elderly, a high dose formulation of the commonly used trivalent inactivated influenza vaccine (IIV) was tested in a large-scale Phase 3 clinical trial dubbed FIM12. In new research, a high-dose influenza vaccine produces a stronger immune response than the standard vaccine in frail seniors under care in nursing homes. All patients ineligible for Fluzone High-Dose should be offered standard- dose inactivated influenza vaccine free-of-charge.Gravenstein and colleagues (July 2017)1 found that in a large cluster-randomised trial of elderly populations residing in nursing homes, Fluzone High-Dose was High-dose trivalent influenza vaccine compared to standard dose vaccine in elderly adults: safety, immunogenicity and relative efficacy during the 2009-2010 season.Safety and immunogenicity of a high dosage trivalent influenza vaccine among elderly subjects. High-dose influenza vaccine is 24 percent more effective than the standard- dose vaccine in protecting persons ages 65 and over against influenza illness and its complications, according to a Vanderbilt-led study published this week in the New England Journal of Medicine (NEJM). Higher doses also increased the number of elderly volunteers achieving levels of antibody that have been associated with protection against influenza. Moreover, the vaccine was well-tolerated at all dosage levels.
