The study is comparing two vaccines: the investigational vYF vaccine and the already available Stamaril vaccine. Both vaccines are designed to protect against Yellow Fever by helping the body build immunity to the virus.

The purpose of the study is to compare the immune response generated by the vYF vaccine to that of the Stamaril vaccine. Participants will receive one dose of either the vYF vaccine or the Stamaril vaccine. The study will monitor the participants’ immune response over time, specifically looking at how well their bodies produce antibodies, which are proteins that help fight infections. The study will also track any side effects or reactions to the vaccines.

Participants in the study will be observed for a period of time to assess the effectiveness and safety of the vaccines. This includes checking for any immediate reactions after vaccination and monitoring for any side effects over the following months. The study aims to ensure that the new vYF vaccine is as effective and safe as the existing Stamaril vaccine in providing protection against Yellow Fever.

]]> Study Comparing Different Injection Methods of Yellow Fever Vaccine in Adults https://clinicaltrials.eu/trial/study-comparing-different-injection-methods-of-yellow-fever-vaccine-in-adults/ Wed, 29 Apr 2026 15:05:46 +0000 https://clinicaltrials.eu/trial/study-comparing-different-injection-methods-of-yellow-fever-vaccine-in-adults/ This clinical trial is focused on studying yellow fever, a viral infection transmitted by mosquitoes, which can cause symptoms ranging from fever and chills to more severe complications. The study will use a vaccine called STAMARIL®, which contains a live, weakened form of the yellow fever virus strain 17D-204. The purpose of the study is to compare how well the vaccine works when given through different methods: under the skin (intradermal), into the muscle (intramuscular), and under the skin (subcutaneous).

Participants in the study will receive the STAMARIL® vaccine in one of these three ways. The study will observe the body’s immune response, specifically looking at the presence of certain immune cells in the skin and blood after vaccination. The study will also monitor any side effects that occur after receiving the vaccine. The goal is to understand which method of vaccination is most effective in producing a strong immune response against yellow fever.

The study will take place over a period of time, with participants being monitored for their immune response and any side effects up to 120 days after vaccination. This research aims to provide valuable information on the best way to administer the yellow fever vaccine to ensure maximum protection against the disease.
