The UK Vaccine Network project is a £110 million ODA-funded project which makes targeted investments to support the development of new vaccines and vaccine technologies for emergent infectious disease threats in low and middle-income countries. This will allow outbreaks of diseases with epidemic potential to either be prevented through proactive vaccination campaigns or controlled through quick development of new vaccines and/or responsive vaccination campaigns upon outbreak detection. An investment strategy for the project was developed using advice from the UK Vaccine Network, a group of experts from academia, industry, government and philanthropic organisations, chaired by the DHSC Chief Scientific Adviser
