The Baseimmune founders have spent their entire lives obsessing about vaccines. It is only recently that the rest of the world has caught up with them.

Josh and Ari met at the Jenner Institute in Oxford where they were both studying for their PhDs in vaccinations. During late nights spent in the lab, they realised there was a massive opportunity to put machine learning at the heart of vaccine development, specifically when it came to antigens.

A vaccine has two components.

An adjuvant and an antigen.

The antigen mimics the virus, and the adjuvant is the delivery vehicle and boosts your immune system against the virus it has just received.

Or as Josh puts it in Formula One terms: the antigen is the driver and the adjuvant is the car. The problem is that nobody has been trying to make the driver better. All the investment has focused on the car.

And bad driving helps explain why many vaccines are unable to respond to future mutations of the virus. They are good at inducing antibodies initially, but as the virus changes, the antibodies no longer recognise the new variants. Baseimmune are changing this.

Antigens take certain parts of the virus, which the make your body develop the right antibodies. The key question is: what parts of the virus should the antigen take? Josh realised the need to build a machine learning platform that could answer this question. And because viruses mutate — a platform that would predict how a virus will change, and create an antigen that is variant-proof.

Josh asked his childhood friend and self-taught computer scientist Phil, to join the founding team, and together they developed Baseimmune. Being at the centre of the Oxford ecosystem they have already licensed their antigens to Vaccitech to develop an HPV vaccine. The vaccine is already in pre-clinical trials. Vaccitech, helped AstraZeneca develop the Covid vaccine, and recently announced their $168mm Series B helped AstraZeneca.

The founders have a strong track record developing vaccines. The team have developed 15 vaccines between them, two of which are in Phase 1 clinical trials. Josh is responsible for the world’s first therapeutic HPV vaccine, helping prevent the development of HPV-related cancer.
