Official title
Transcriptomic Signatures of Influenza Vaccine Responses
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research study is to better understand the immune response to the Adjuvanted Subunit flu vaccine (MF59) and the High Dose flu vaccine (HDFlu) in people 65 years of age and older. The research team will be studying why immune response diminishes as people get older in both men and women. The ultimate goal is to understand how flu immunity develops after vaccination. This information may lead to the development of more effective flu vaccines in the future.
