Flu vaccine response in older adults who get it yearly
Part of Infections, Lungs & breathing clinical trials.
This study checks how well the seasonal flu vaccine works in people 65 and older who have had flu shots regularly. It compares their immune response to that of younger adults to see if repeated vaccination still protects them.
