I hear you. I just discovered today that there's another EO, EO 14042, that muddies up the water for EO 14043. My other half is currently fighting this battle and I've been trying to help. It seems pretty clear-cut to me that any sort of vaxx mandate is illegal, as all of the jabs available in the US are EUA. It violates the Nuremberg code and also Federal law:

"EUA products are by definition experimental and thus require the right to refuse. Under the Nuremberg Code, the foundation of ethical medicine, no one may be coerced to participate in a medical experiment. Consent of the individual is “absolutely essential.” A federal court held that the U.S. military could not mandate EUA vaccines to soldiers. Doe #1 v. Rumsfeld, 297 F.Supp.2d 119 (2003). The court held: "...the United States cannot demand that members of the armed forces also serve as guinea pigs for experimental drugs." Id. at 135. No court has ever upheld a mandate for an EUA vaccine."
