Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Eighty participants will be recruited to this study. Participants will be randomly assigned to one of four different groups (study arms). Each group will receive both study vaccines and placebo but at different times. All NYVAC-B vaccine doses will be the same, but the doses of the rAD5 vaccine will differ from group to group. Some participants in each group will receive only placebo. Participants will visit the study clinic about 13 times over the course of 12 months and be contacted for follow-up for 4 years.
All study injections will be given in the same upper arm area. There will be a total of four injections during the course of the study. After each injection, participants will need to stay in the clinic for at least 25 minutes to check for any adverse reactions. Additionally, participants will need to monitor their own health on the evening after the injection and for the next three evenings, by taking their temperature and making notes of any noticed side effects. Tools will be provided to accomplish both of these tasks. During these few days following the injection, study investigators will need to maintain contact with participants (the participant will specify the best mode of contact).
Certain clinical procedures will be performed during the course of this study including regular HIV testing and counseling, physical exams, collection of blood and urine, pregnancy tests if applicable, questions about health and medications, questions about HIV risk and sexual behaviors, and any personal problems or benefits participants may have experienced from participating in the study.
