Study Summary

Background: The flu is a common viral infection that can be deadly for certain people. Vaccines against flu have been developed to teach the body to prevent or fight the infection. A new vaccine may help the body to make an immune response to H1 flu, a flu strain that infects humans. Objective: To test the safety and effectiveness of the H1 Stabilized Stem Ferritin vaccine (VRC-FLUNPF099-00-VP). Eligibility: Healthy people ages 18-70 years old who got at least 1 licensed flu vaccine since January 1, 2014. Design: Participants received 1 or 2 vaccinations by injections (shots) in the upper arm muscle over 4 months. Participants received a thermometer and recorded their temperature and symptoms every day a diary card for 7 days after each injection. The injection site was checked for redness, swelling, or bruising. Participants had 9-11 follow-up visits over 12-15 months. At follow-up visits, participants had blood drawn and were checked for health changes or problems. Participants who reported influenza-like illness had nose and throat swabs for evaluation of viral infection. Some participants had apheresis. A needle was placed into a vein in both arms. Blood was removed through a needle in the vein of one arm. A machine removed the white blood cells and then the rest of the blood was returned to the participant through a needle in the other arm. A separate consent was provided to participants for genetic testing on their samples.

Primary Outcome

Participants recorded the occurrence of solicited symptoms on a diary card for 7 days after each study product administration and reviewed the diary card with clinic staff at a follow up visit. Participants were counted once for each symptom at the worst severity if they indicated experiencing the symptom more than one time at any severity during the reporting period. The number reported for "Any Local Symptom" is the number of participants reporting any local symptom at the worst severity. Reac
