Influenza Immunization in Adults Over Age 75
NCT02200276
This study is recruiting at 1 US site in 1 state, according to its ClinicalTrials.gov record last updated .
Summary
The immune system is the part of the body that protects against infection. The immune system often doesn't work as effectively as people get older. This research is being done to find out how the immune systems in older people who are over age 75 respond to influenza vaccine (flu shot). We also want to find out if chronic cytomegalovirus (CMV) infection, a common virus infection in older persons affects the immune response in people older than 75 years of age who receive a flu shot.
