Study Type: Interventional




Official Title: Immunogenicity and Safety of Yellow Fever Vaccine (Stamaril®) Administered Concomitantly With Tetravalent Dengue Vaccine in Healthy Toddlers at 12-13 Months of Age in Colombia and Peru

Brief Summary:

The study is designed to evaluate whether the first CYD dengue vaccination can be administered concomitantly with Stamaril® yellow fever vaccine during the same day and visit, but at 2 different sites of administration.

Primary Objective:

  • To demonstrate the non-inferiority of the immune response against Yellow Fever in flavivirus (FV)-naïve subjects at baseline receiving one dose of Stamaril vaccine administered concomitantly with the first dose of CYD dengue vaccine compared to subjects receiving one dose of Stamaril vaccine concomitantly with placebo.

Secondary Objectives:

  • To assess the non-inferiority of yellow fever immune response 28 days post-Stamaril vaccination based on seroconversion rates regardless of the FV status of subjects at baseline.
  • To describe the safety of Stamaril vaccine administered concomitantly with the first dose of CYD dengue vaccine, or Stamaril administered concomitantly with placebo.
  • To describe the safety of CYD dengue vaccine after the first dose of CYD dengue vaccine administered concomitantly with Stamaril vaccine or CYD vaccine administered alone.
