That the powerful nerve agent A-234 would have been prescribed as an antidote to the rather less potent nerve agent BZ may seem improbable, but it must be remembered that the Salisbury Trust Hospital where the Skripals were treated is within seven miles of Britain's Chemical and Biological Weapons Research establishment at Porton Down, where doctors at the Salisbury hospital might well have sought advice on treatment for apparent nerve agent poisoning.
Certainly, the Porton Down lab must have a supply of A-234 on hand, since it was able to identify Novichok in samples provided by the police or Salisbury hospital, and for that they would have required a sample of authentic A-234 for comparison.
That BZ was the poison and A-234 the antidote, is consistent with the letter to the Times newspaper in which the Salisbury Trust Hospital's Resident in Emergency Medicine, Dr. Stephen Davies, stated that no one had been treated at the hospital for nerve agent poisoning. That would make sense if BZ, which is a readily available pharmacological agent, was considered to be just that, a pharmacological agent — not a WMD or nerve agent. Then Dr. Davies letter can be interpreted to mean that the Skripals were treated not for nerve agent exposure, but by nerve agent exposure.
The truth of what happened to the Skripals in Salisbury the day they were admitted to hospital for treatment of poisoning is unlikely ever to be known with any certainty unless the physicians and others who attended on the Skripals are allowed to come forward and provide evidence. So far, it appears they have been effectively gagged.
Specifically, one would like to know from the hospital staff whether they can confirm the claim of the "doctor," who attended on the Skripals in the park where they were stricken (and who requested that her identity not be disclosed) that the Skripals were vomiting and convulsing when admitted to hospital, i.e., showing symptoms of A-234 poisoning.
In addition, one would like to know (a) what treatments, including drugs, were applied to these patients, and (b) what analyses of blood and vomit or stomache contents were ordered by the attending physicians a the time the Skripals were admitted to the Salisbury Trust Hospital, and (c) what did those tests show?
As we wait for answers to such questions from the Government of Theresa May, we will not hold our breath.
