This clinical trial is looking at the safety and how well a new vaccine works in healthy adults aged 18-55 who do not have HIV. The study involves a priming dose of the vaccine followed by booster doses. "Adjuvanted" means something is added to the vaccine to help it work better. The study aims to see if the booster helps the body make strong antibodies, which are proteins that fight infections.
To join, participants must be in good health, not pregnant, and not have HIV. They must agree to use birth control and attend all clinic visits. The study will measure blood pressure, test for diseases like hepatitis, and check for overall good health.
- Participants will visit the clinic several times for follow-ups.
- Compensation may be provided for time and travel.
- Potential risks include common vaccine side effects like soreness or mild fever.
