Venn’s Paris team are highly regarded in the field as one of the leading providers in this area which is a perfect complement to the London offering.

“We are delighted to be conducting this influenza challenge study, recent events have highlighted the importance of treatments for viral infections such as influenza and we are seeing an increased level of interest amongst both pharma and biotech in developing innovative new vaccines, antivirals, and therapeutics.


The Company is pleased to be continuing to deliver on our pipeline of opportunities. This has been due to the exceptional work from the hVIVO team, building on the Company’s long history as the world leading challenge study provider. Both the team and I are excited to see the progress being made by the Group and look forward to continuing the momentum as we rapidly grow the business to maximise shareholder value.”
