What is the purpose of this trial?


We need to develop new technologies to achieve rapid clinical development of safe and effective vaccines.

We are carrying out a clinical trial of a new mRNA vaccine targeting the Omicron BA.1 variant of COVID-19 called NeomiVac. If NeomiVac is shown to be safe and capable of inducing an immune response, then this technology can be used on newer variants of COVID-19 and/or different diseases. This could rapidly accelerate the development of new vaccines against future pandemics and greatly reduce the time taken for new mRNA vaccines to reach patients. There is also potential for this technology to produce vaccines that tackle infections that cannot be treated with current antibiotics due to antibacterial resistance. This could transform the ability to treat bacterial infections globally and save millions of lives.

Whilst NeomiVac is frozen and stored at -80 °C, preliminary data show it may have the potential to be stable for longer at fridge temperature compared with existing mRNA vaccines. If the long-term stability at fridge temperature is confirmed, it would greatly reduce cost, and simplify distribution of mRNA vaccines globally, specifically in low- and middle income countries, where there may be limited facilities and infrastructure available.

The purpose of this study is to test NeomiVac for the first time in healthy volunteers aged 18 64 years. The trial will give us valuable information on the safety of the vaccine and the immune response it creates in healthy volunteers and will involve giving participants one dose of the vaccine and then following them up over 6 months.
