Background:

Influenza (flu) is a contagious respiratory illness. It is caused by influenza viruses that infect the nose, throat, and sometimes the lungs. Vaccines are given to teach the body to prevent or fight infection. Researchers want to study a new vaccine to prevent the seasonal flu.

Objective:

To see if the FluMos-v1 vaccine is safe and how the body responds to it.

Eligibility:

Healthy adults ages 18-50 who received at least one licensed flu vaccine from 2016 through the 2019-2020 influenza season.

Design:

Participants will be screened through a separate protocol.

Participants will be tested for COVID-19. They may have a pregnancy test.

Participants will receive the FluMos-v1 vaccine or the Flucelvax vaccine. It will be injected in the upper arm.

Participants will complete a diary card for 7 days. They will record any symptoms they have. They will be given a thermometer to check their temperature. They will also be given a ruler to measure any skin changes at the injection site.

Participants will have about 10 study visits. They will be asked how they are feeling and if they have taken any medications. They will have blood drawn.

Participants will have oral mucosal samples collected using a thin swab. They may have nose and throat secretions collected using a thin swab.

Some participants will have optional apheresis. Blood will be removed through a needle in a vein in one arm. A machine will separate the white blood cells. The rest of the blood will be returned through a needle in a vein in the other arm.

Participation will last for 40 weeks.
