MOD publishes clinical findings in 111 ex-porton down volunteers

A two-year medical study of Porton Down veterans has found no clinical evidence linking ill-health with participation in a volunteer programme at the research establishment.

111 former volunteers were referred to the Porton Down Volunteers Medical Assessment Programme (PDVMAP) at St Thomas' Hospital, London, between February 2001 and July 2003.

Most had taken part in a 1950s research programme which involved exposure to single dose low concentrations of chemical warfare agents.

Professor Harry Lee, head of the PDVMAP, published his findings today. Key among these findings are:

  • No clinical evidence has been found linking ill-health with participation in the research programme.
  • No unusual patterns of disease have been identified among volunteers medically assessed.
  • Illnesses observed within volunteers are consistent with those you would expect to find in a pool of men from the general population of similar age.

Professor Lee said:

"On a clinical basis, we could find nothing to support the idea that participation in the Porton Down Volunteer Programme had produced any adverse long term health effects."

"Similarly, we were unable to find any unusual patterns of disease."

Ivor Caplin, Under Secretary of State for Defence, said:

"We welcome Professor Lee's studies and hope these results will be reassuring to volunteers who made such vital contributions to important research at Porton Down.

"However, we also recognise that some volunteers may still have worries about their participation in the volunteer programme. We shall continue to work closely with those people and listen to their concerns."

Notes To Editors

  1. The PDVMAP was established in February 2001 to investigate the concerns of former volunteers who felt their ill-health might be linked to their participation in the Volunteers Programme at Porton Down, Wiltshire, in the 1950s.
  2. All volunteers who took part in the assessment programme were independently referred by their GPs. Information obtained was analysed to determine whether clinical diagnoses and symptoms reported had any relationship to chemical exposures.
  3. Although an MoD programme, it was conducted by physicians operating in total independence of the department. MoD had no say in the structure of the programme or the results contained within Professor Lee's paper.
  4. The MoD has a dedicated helpline for former volunteers concerned about their participation in the programme -0800 783 2521.
