Clinical trials

The purpose of the trial is to evaluate the safety, efficacy and immunogenicity of up to 3 intramuscular injections of the Acne mRNA vaccine candidate at up to four dose levels in adult participants aged 18 to 45 years with moderate to severe acne. This trial will consist of a Core Study followed by an optional Long-Term Extension (LTE). The Core Study will consist of: * Two cohorts evaluating the 2-administration regimen (Cohorts A): Sentinel Cohort A and Main Cohort A. * Two cohorts evaluating the 3-administration regimen (Cohorts B): Sentinel Cohort B and Main Cohort B. Participants from Sentinel Cohorts A and B and from Main Cohort A will be invited to an additional 30-month follow up after completing their last planned Core Study visit to assess the long-term effects of the vaccine. Participants from Main Cohort B will be invited to another LTE study managed through a separate protocol.

The primary objective of this study is to assess maternal, obstetrical, pregnancy, and neonatal and infant outcomes among women and their offspring(s) vaccinated with Dengvaxia during their pregnancy

Primary Objective: To assess maternal, obstetrical, pregnancy, and neonatal and infant outcomes among women vaccinated with MenQuadfi® during pregnancy or in the 30 days preceding their Last Menstrual Period (LMP).

The purpose of the VBE00009 study is to evaluate the safety, efficacy and immunogenicity of 2 administrations of the Acne mRNA vaccine candidate at single dose level in participants aged 18 to 45 years with mild acne. This study will consist of a Core Study followed by an optional Long-Term Extension (LTE). Core Study will include a Sentinel Cohort and a Main Cohort, with the Sentinel Cohort assessing the safety in a stepwise manner. If the participants consent to the LTE, they will be followed up for an additional 30 months after the last planned visit in the Core Study, to assess the long term effects of the vaccine.
