NCT01654224

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Non-inferiority of High-dose Inactivated Influenza Vaccine(HDIV) Versus Standard Dose Inactivated Influenza Vaccine(SDIV) Among Residents of Long Term Care(LTC) Settings

    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.

    30 days

  • Non-inferiority of High-dose Inactivated Influenza Vaccine(HDIV) Versus Standard Dose Inactivated Influenza Vaccine(SDIV) Among Residents of Long Term Care(LTC) Settings
