Influenza Clinical Trial
Official title:
Inpatient Surveillance for Influenza Infections in Adults
Influenza vaccination is recommended for all persons age 65 and older. Vaccines that are designed and tested in young healthy adults are often not as effective when used in the elderly. This study will be a one year pilot study to see if it would be practical to conduct a larger study at several other hospitals in the future. Study participants will include 350 men and women greater than or equal to age 50 that are hospitalized at Vanderbilt University or Baptist Community Hospital with acute respiratory symptoms. Study procedures will include questions, one nasal swab, one throat swab, and chart reviews after the patient has been released from the hospital. The nasal and throat swabs will be tested for influenza A and B viruses.
