  Purpose

The purpose of the study is to compare the performance of two currently available influenza (flu) vaccines. This study will try and determine if the high dose flu vaccine provides protection that is the same or better than that of regular dose flu vaccine. Both the regular dose and the high dose flu vaccines are approved by the FDA for use in older adults.

Primary Outcome Measures:
  • Non-inferiority of high-dose inactivated influenza vaccine(HDIV) versus standard dose inactivated influenza vaccine(SDIV) among residents of long term care(LTC) settings [ Time Frame: 30 days ] [ Designated as safety issue: No ]
    The primary objective of this study is to determine the noninferiority of high- dose inactivated influenza vaccine (HDIV) versus standard dose inactivated influenza vaccine(SDIV)among residents of long term care(LTC)settings.Non-inferiority will be determined by comparing baseline and one month post vaccination HAI and MN titers using non-inferiority analysis.


Secondary Outcome Measures:
  • Non-inferiority and immunoprotection persistence at 6 months and the impact of potential immune modulators on titer response [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Compare the immunogenicity via HAI and MN titers for HDIV and SDIV at 6 months in frail LTC residents and potential modifiers of immune response

Arms Assigned Interventions
Active Comparator: High Dose Inactivated Influenza Vaccine
For HDIV,0.5 ml of high dose inactivated influenza vaccine consisting of a total of 180mcg (60 mcg each strain) of influenza virus hemagglutinin
 Biological: High Dose Inactivated Influenza Vaccine
0.5 ml HDIV consisting of 180 mcg (60 mcg each strain) of influenza virus hemagglutinin

 Biological: Standard Dose Inactivated Influenza Vaccine
0.5 ml of standard dose inactivated influenza vaccine consisting of a total of 45 mcg (15 mcg each strain) of influenza virus hemagglutinin

Detailed Description:

Influenza and pneumonia are the fifth leading cause of death in the United States, the leading cause of vaccine preventable death, and the leading cause of infection related deaths among nursing home residents(Nace, Drinka et al.2010). Each year, an estimated 36,000 individuals die from seasonal influenza and over 90% of these deaths occur among older adults, primarily the frail older adults residing in LTC settings(Fiore,Uyeki et al. 2010).Vaccination is the most effective means of preventing influenza (Nichol and Treanor 2006). Despite increasing success in immunizing LTC residents though, outbreaks continue to occur annually with case fatality rates ranging between 5-55% (Nace 2008). Older adults have a reduced response to influenza vaccination, in part due to age related immunosenescence (Keitel, Atmar et al. 1121; Skowronski, Tweed et al. 2008). It is widely recognized that more effective vaccine options are needed for frail older adults. One option is to increase the hemagglutinin (HA) dose in influenza vaccines in an effort to increase antibodies to hemagglutinin. To date, no studies have evaluated the effectiveness of the HDIV among LTC residents.
