Study Background Participate in a compensated research study that will help Johns Hopkins researchers test a new type of vaccine for COVID-19. Healthy adult volunteers ages 18-50 are needed to test the safety, tolerability, and immune response of an intra-nasal COVID-19 vaccine. Intra-nasal means the vaccine will be taken as a spray in the nose, like a flu vaccine you may have gotten, and no needles are involved. Enroll in our compensated study today! |
