The purpose of the study is to test an experimental HIV vaccine. The study vaccine is made from two parts: a man-made piece of protein that looks like a protein found on the outside of HIV and an adjuvant. An adjuvant is a substance that helps the immune system respond better. The study will see if the protein and two different amounts of the same adjuvant…

This study is studying the effectiveness and safety of a new birth control pill. The pill contains two hormones, drospirenone (a progestin) and estetrol (an estrogen), which combine to prevent pregnancy. Scientists think that estetrol may be safer and have more benefits than other estrogen hormones. The study lasts about one…

PrEP (Pre-Exposure Prophylaxis) is medication that is taken to prevent HIV if a person is exposed to HIV. Research is ongoing to develop PrEP medications that may be both convenient and effective. This study is important because people who inject drugs face multiple overlapping individual, social, legal, and structural challenges contributing to a…
