ClinConnect Summary

This clinical trial is studying a new vaccine called BIMERVAX® to see how safe it is and how well it helps protect against COVID-19 in adolescents aged 12 to under 18 years. The study will include 300 participants who have already received two doses of the Comirnaty vaccine at least six months prior. To be eligible, participants must be generally healthy or have stable, non-serious health conditions, and they need to have a negative COVID-19 test before they receive the BIMERVAX® booster.

Participants in the trial will be followed for a year, during which they'll attend regular check-ups. They will receive the BIMERVAX® vaccine and be monitored for any side effects or reactions. This study aims to ensure that the new booster is as effective and safe as other vaccines currently available. Parents or guardians will need to provide consent, and participants will also need to agree to follow some guidelines, particularly around pregnancy prevention for those who can conceive. Overall, this trial will help gather important information on how well BIMERVAX® can protect adolescents against COVID-19.

  • • History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (e.g. anaphylaxis) to any component of the study intervention(s).
