Official title

Comparisons of the Reactogenicity and Immunogenicity in Ambulatory Elderly Subjects of a Standard-Dose Fluzone® (15 µg HA/Virus Strain) and a High-Dose (60 µg HA/Virus Strain) of a Trivalent Inactivated Influenza Virus Vaccine

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to compare a new higher-dose influenza virus vaccine to the standard dose vaccine in elderly adults who can walk. Current influenza vaccines protect elderly against viral influenza but not as well as desired. It is expected that the higher doses vaccine can be given with little reaction, but this needs to be tested. Up to 410 people ages 65 years and older will be recruited from the community and from existing volunteer populations. Participants will receive either the high or standard dose injected in the muscle, remain in the clinic for 20 minutes afterward, and maintain a daily memory aid for 7 days. The memory aid will be reviewed by telephone 8-12 days after the injection and return to the clinic or contacted by telephone 6 months after the injection.
