You assume they are the same drug. You have no way of knowing. One has EUA and the other hasn't been manufactured yet. One is not liable for death or injury, the other not manufactured yet and they are liable. So, which will they use? The EUA and claim it's fully approved to get people to take it. Meanwhile the approved one hasn't been made. Sounds like a game of 3 card monte to me. Here's the way it works. Somebody who has been hesitant thinks it's fully approved and gets the jab. They die. Family cannot sue. Why? Pfizer claims immunity because of EUA. The full authorization is needed to convince corporations and the military to use it. Any death or injury that they should be liable for will get pitched because they'll claim it was from the earlier stockpile that had EUA. Heads they win, tails you lose.
