Since the discovery of the virus strain, as being similar (or identical, depending which report one reads) to that used/kept at Pirbright research facility, the Protection Zone around the farm has been expanded today. The Pirbright facility is about 3 miles from the affected farm, so this new expanded zone includes the area around Pirbright and again has a 3km radius (interesting that the affected farm was THREE MILES from Pirbright (5km) so this area may be too small) and a new surveillance zone with a 10km radius from both sites.

Readers will be comforted that the head of the IAH at Pirbright has told reporters that there have been "no breaches of our procedures". Merial have apparently voluntarily ceased production of vaccines at the site.
