The Saudi ambassador, Muhammad al-Qahtani, gave a speech at a conference in Cairo, but collapsed and died. It is not easy to find information on his Covid vaccine status, but it is a fair guess that he was fully vaxxed, like so many leading figures who have been collapsing. Steve Kirsch has videos documenting this. In my time I have never seen anything like this.
