Valneva Booster

Have you been vaccinated for COVID-19 but did you not yet get a booster vaccine? Or have you had COVID-19 but have you not been vaccinated yet? Then we are looking for you for a study on the new, traditionally developed, COVID-19 candidate booster vaccine from Valneva!

Inactivated virus vaccine
The Valneva candidate booster vaccine is a so-called inactivated virus vaccine. This vaccine contains inactivated (“dead”) virus particles. The virus has been modified in such a way that it can no longer infect someone. In contract to an mRNA vaccine, the Valneva vaccine teaches the body to recognize the entire virus.

What does participation entail?
The study starts with a telephonic screening. Next is the first study visit including administration of the vaccine. During the 7 days following the first visit you will keep a diary. Exactly 2 weeks and approximately 6, 9 and 12 months after the first visit, we will schedule following study visit. If you fully participate in the study, you will receive a compensation of €500. In addition, you will receive a QR code to show that you have received a booster vaccine.

Are you interested to participate in the study? Or would you like more information? Please have a look at our website:
