Peter Wildy and Sir Gordon Wolstenholme wrote: Subsequent investigations and reactions The Shooter inquiry An official government inquiry into Parker's death was conducted by a panel led by microbiologist R.A. Shooter, and comprising Christopher Booth, Sir David Evans, J.R. McDonald, David Tyrrell and Sir Robert Williams, with observers from the World Health Organization (WHO), The Health and Safety Executive and the Trades Union Congress. The inquiry's report noted that Bedson had failed to inform the authorities of changes in his research that could have affected safety. Shooter's enquiry discovered that the Dangerous Pathogens Advisory Group had inspected the laboratory on two occasions and each time recommended that the smallpox research be continued there, even though the facilities at the laboratory fell far short of those required by law. Several of the staff at the laboratory had received no special training. Inspectors from the WHO had told Bedson that the physical facilities at the laboratory did not meet WHO standards, but had nonetheless only recommended a few changes in laboratory procedures. Bedson misled the WHO about the volume of work handled by the laboratory, telling them that it had progressively declined since 1973, when in fact it had risen substantially as Bedson tried to finish his work before the laboratory closed. Shooter also found that while Parker had been vaccinated, it had not been done recently enough to protect her against smallpox. A foreword by the Secretary of State for Social Services, Patrick Jenkin, noted that the University of Birmingham disputed the report's findings. The report concluded that Parker had been infected by a strain of smallpox virus called Abid (named after the three-year-old Pakistani boy from whom it had originally been isolated), which was being handled in the smallpox laboratory during 24–25 July 1978. It found that there was "no doubt" that Parker had been infected at her workplace, and identified three possible ways in which this could have occurred: air current transmission; personal contact; or contact with contaminated apparatus. The report favoured air current transmission and concluded that the virus could have travelled in air currents up a service duct from the laboratory below to a room in the Anatomy Department that was used for telephone calls. On 25 July, Parker had spent much more time there than usual ordering photographic materials because the financial year was about to end. Since Shooter's Report potentially played an important role in
