Study Summary
Background: * Adenoviruses are viruses that typically cause symptoms of a cold or eye infection. These viruses are being tested as part of a possible new vaccine. Researchers hope that the adenovirus will help carry the vaccine into the body and cause an immune response. An immune response is the body s release of cells and substances that protect the body from infection. If an adenovirus vaccine can be developed, it might be used as part of a vaccine for malaria or other serious illnesses. Researchers want to test the adenovirus vaccine as a nasal spray in healthy volunteers. The vaccine is called AD4-H5-VTN. * Because the vaccine contains a live adenovirus, there is a possibility that participants can infect other people. Therefore, participants' intimate contacts must join this study. An intimate contact is someone who the participant will kiss on the mouth or have sexual intercourse with during the period of this study. Objectives: * To study the immune response of the AD4-H5-VTN vaccine in healthy volunteers. * To see if the adenovirus in the AD4-H5-VTN vaccine is contagious or spreads to others. Eligibility: * Healthy volunteers between 18 and 49 years of age. * Intimate contacts of healthy volunteers between 18 and 65 years of age. * Participants must not have evidence of previous exposure to adenovirus type 4. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. * Participants who will receive the vaccine must be willing to be hospitalized for between 5 and 7 days. They will come to the National Institutes of Health for follow-up visits weekly for the first month, after 8 weeks, in 6 months, and possibly 1 year. They must also avoid all vaccines (including seasonal flu vaccine) and allergy shots for 30 days before and after having the study vaccine. * Participants will enter the hospital for the vaccine study visit. They will receive the vaccine as a nasal spray. Because the vacci
