I'D BE CURIOUS TO KNOW WHAT THE "TECHNICAL REASONS" BARDA PROVIDED TO PLURISTEM IN THEIR REJECTION. WHATEVER IT/ THEY WERE IT COULD INFLUENCE ONGOING STUDIES ELSEWHERE AND PUT A BIG QUESTIONMARK OVER THE USE OF THE STEMS IN AN EMERGENCY OR TO TREAT PNEUMONIA. I'D EXPECT A CLEARER EXPLANATION ON THE QUESTION FROM THE COMPANY. IT LEAVES TO MUCH TO WONDER ABOUT.
