Follow Up measured through participants' last study visit at 6 to 13 months, depending on when participants enroll in the study
Summary
This trial is testing two types of weakened RSV vaccines in children to see if these vaccines can safely help their bodies learn to fight off the virus.
Who is the study for?
This trial is for children aged 6 to 59 months who have either been previously exposed to RSV (seropositive) or not (seronegative). Participants must be in good health, with normal growth and up-to-date vaccinations. They cannot join if they were born very prematurely, have a history of severe vaccine reactions, chronic diseases, immune system problems, or recent use of certain medications.
What is being tested?
The study tests two live-attenuated RSV vaccines: RSV 6120/∆NS1 and RSV 6120/F1/G2/∆NS1 against a placebo. It aims to assess how well these vaccines create an immune response in young children and monitor their safety.
What are the potential side effects?
Possible side effects are not detailed but may include typical vaccine-related reactions such as soreness at the injection site, fever, irritability, and mild respiratory symptoms. Severe allergic reactions are rare but possible.

Side Effect Profile
Prior Approvals
Other Research
The most common treatments for Respiratory Syncytial Virus (RSV) include supportive care, antiviral medications, and vaccines. Supportive care involves managing symptoms and ensuring adequate oxygenation and hydration.
Antiviral medications like ribavirin can inhibit viral replication, though their use is limited. Live-attenuated vaccines, such as RSV 6120/∆NS1 or RSV 6120/F1/G2/∆NS1, work by stimulating the immune system to recognize and fight the virus without causing the disease.
These vaccines are designed to be safe and effective, especially in young children who are at high risk for severe RSV infections. By inducing a strong immune response, these vaccines can potentially reduce the incidence and severity of RSV infections, thereby decreasing hospitalizations and improving patient outcomes.
