Good old Tony. Perhaps he's forgotten that the license as issued by the MHRA is for use of the vaccine as proven in trials ie two doses at regulated interval between first and final dose. To use as he suggested would probably be 'off license use' therefore the person authorising would be responsible for any problems occurring.
Surprised that a lawyer would make such off the cuff comments. There again there was a rumour that he talked up that Saddam had enough firepower to make him threat to our security.
