Porton Down: Can this laboratory help stop the next pandemic?
One of the UK's most secretive centres of scientific research - Porton Down - is aiming to stop the next pandemic "in its tracks".
James Gallagher, Health and science correspondent, passed through the incredibly tight security at this remote facility to get rare access to its scientists.
They are based in the shiny new Vaccine Development and Evaluation Centre.
Their work builds on the response to Covid, and aims to save lives and minimise the need for lockdowns when a new disease next emerges.
