The Company


Vaccitech plc is a fast-growing biotech company. At only six years old we already have a development portfolio of nine programmes, including a partnered product that is in commercial production and that has seen more than 3 billion doses administered worldwide and an IPO behind us. We are a publicly listed clinical stage biopharmaceutical company that spun out of the University of Oxford’s Jenner Institute, one of the most prestigious vaccine research centres in the world. We discover and develop immunotherapeutic products and vaccines for the treatment and prevention of infectious diseases, cancer, and autoimmunity. Our achievements include co-inventing and jointly developing our COVID-19 vaccine candidate VTP-900, now Vaxzevria, which we assigned to Oxford University Innovation to facilitate the licensing of those rights to AstraZeneca. We run clinical studies to explore treatments for patients with HBV and HPV infections and are developing rapid and scalable manufacturing processes for our platforms.


In December 2021, Vaccitech acquired Avidea Technologies Inc. with exciting product candidates for oncology and autoimmunity based on the innovative SNAPvax platform, which has demonstrated unprecedented control over T cell induction. This gives us U.S operational presence in Maryland, complements Vaccitech’s established capabilities and reinforces our position as a fast-growing global leader in immunotherapies and vaccines. Vaccitech's UK headquarters has recently moved to a state-of-the-art facility in the UK's leading science and innovation campus at Harwell. We conduct research globally and have ambitious plans in the UK and US, where we will continue to grow our teams over the coming months and years.
