UK Health Security Agency: Porton Down

Debate between Chris Vince and Ashley Dalton

Wednesday 21st May 2025 Commons Chamber

[The Parliamentary Under-Secretary of State for Health and Social Care (Ashley Dalton)]

I thank the right hon. Member for Salisbury (John Glen) for securing this important debate and for his passionate advocacy on behalf of his constituents for the vital work conducted by the UK Health Security Agency at its Porton Down site. I also take the opportunity to recognise the intervention from my hon. Friend the Member for Harlow (Chris Vince) and his passionate advocacy on behalf of his constituents.

Before I come to the decision-making process, I want to use this opportunity to reference some of the incredible work that takes place on the site. Whether it is advancing vaccine development to address global health threats, such as Mpox, or leading the world in evaluating vaccines to ensure that we have effective programmes that save countless lives, Porton Down stands as a pillar of excellence in our national health security infrastructure.

Through the UKHSA science strategy, we are committed to securing health and prosperity with partners in industry and academia. That is why we established the vaccine development and evaluation centre on the Porton Down site, securing learning from the pandemic and advancing our critical research on vaccines. Porton Down’s diagnostics capabilities are equally vital, providing the UK’s only 24/7 service for detecting rare and imported pathogens, including life-threatening diseases such as Marburg virus, Ebola and Lassa fever. The site also plays a unique role in environmental microbiology and biosafety, helping us to understand better how infections spread in real-world settings.

Porton Down’s role does not stop at healthcare. It reaches into our ecosystems, our food chain and our environment. Porton Down is a national leader in medical entomology, including the surveillance of invasive mosquitoes and ticks. Its work ensures that the UK can rapidly detect and respond to vector-borne diseases, protecting the public from threats before they gain a foothold. The site’s food, water and environmental microbiology teams provide additional expertise that is critical to national resilience and the Government’s work on climate change; but, crucially, the work of those globally leading teams requires the best facilities.

As the right hon. Member will know, many facilities on the site are ageing, and I appreciate that the people who work there need clarity on its future as quickly as possible. The Government are thoroughly assessing options for securing the facilities that are required for these highly specialist functions and services in the future.

[Chris Vince]

I could talk about the benefits of the Harlow site for a long time, and I often do, but on this occasion I will be brief. May I ask the Minister, when the Government are making those decisions, to take account of the fact that the Harlow site is very much shovel-ready and is ideally located, given its strong infrastructure and travel links and its proximity to existing health clusters? The site would very much future-proof this important work.

[Ashley Dalton]

I can assure my hon. Friend that the benefits of all options will be considered.
