Comparing two flu vaccines for older adults
Part of Infections, Lungs & breathing clinical trials.
This study compares two types of flu shots for people 65 and older to see which works better. If you are a Kaiser Permanente member and get your flu shot at a Kaiser facility, this trial looks at your health records to see how well the vaccine protected you.
