Next Generation COVID-19 Vaccine Trial

COVID-19 Investigational Vaccine Trial

The University of Washington is seeking volunteers for a Phase 1 COVID-19 vaccine trial. The purpose of this clinical trial is to test the safety and the body’s immune response to a new type of investigational COVID-19 vaccine called an exosome vaccine.

The study will enroll participants age 18 to 64 who received their primary COVID-19 vaccine series along with at least one booster dose.

The trial will last about 6 months and will involve 9 in-person visits. Participants will undergo a screening assessment to see whether they are eligible. Study visits will involve physical exams, blood draws, nasal swab and saliva collection, and a single vaccine injection. Participants will be asked to keep a diary of their vaccine reactions for 7-days after each injection.

Compensation:
Participants will be compensated $850 for completing the entire study.

Clinic Location:
Our clinic is located on the 11th floor of the Ninth and Jefferson Building at Harborview Medical Center and open Monday through Friday 8am to 5pm.

To be eligible for the trial you must:
▪ Be between 18 to 64 years of age
▪ Have received their primary and booster COVID-19 vaccine

Conditions which would prevent you from participating:
▪ Previous SARS-CoV-2 infection less than 16 weeks ago
