This clinical trial is focused on studying the effects of a medication called sofosbuvir on Yellow Fever, a viral infection transmitted by mosquitoes. The study involves healthy volunteers who will receive a treatment with Sovaldi 400 mg film-coated tablets, which contain the active substance sofosbuvir. Sofosbuvir is known as an RNA polymerase inhibitor, which means it works by blocking the virus from multiplying in the body.
The purpose of the study is to assess how sofosbuvir affects the replication of the YF17D virus, a strain of the Yellow Fever virus. Participants in the study will be monitored for the presence of the virus in their blood and urine, as well as the development of neutralizing antibodies, which are proteins that help fight off infections. The study will also look at any side effects of sofosbuvir, such as changes in liver function tests and blood counts, to ensure the safety of the treatment.
The study will take place over several months, during which participants will receive the medication and undergo regular check-ups to monitor their health and the effects of the treatment. The goal is to gather information on the potential use of sofosbuvir as a preventive treatment for Yellow Fever, especially in situations where vaccination is not possible or practical. This research could provide valuable insights into new ways to protect people from this serious disease.
