About this study

Viruses such as flu and COVID are constantly changing, which means vaccines need to be updated regularly to continue providing effective protection. In these studies, we are investigating vaccines against flu and COVID.

Study 1: Vaccine against flu only. This study investigates a vaccine specifically targeting the flu.

  • A prior COVID vaccine, administered by your own doctor, is permitted.

Study 2: Combined vaccine against flu and COVID. This study investigates the simultaneous administration of a flu vaccine and a COVID vaccine.

  • A prior flu or COVID vaccine, administered by your own doctor, is not permitted for participation.
  • Men and women
  • Age: 18+ or 65+
  • Study 1: A prior COVID vaccine, administered by your own doctor, is permitted.
  • Study 2: A prior flu or COVID vaccine, administered by your own doctor, is not permitted for participation.
  1. Register via the online form; you will receive a confirmation e-mail
  2. Our team will contact you for further follow-up and to assess whether participation is clinically appropriate
  3. Begin participation under medical supervision, including a treatment period and follow-up visits

You will receive personalised guidance from our team of physicians and researchers throughout the study. You are encouraged to ask questions at any stage and will receive support at every step to ensure you feel informed and clinically well-supported.

By participating, you are contributing to important research into vaccines that can better respond to changing viruses and future virus variants.
