I'm O- also and will refuse blood unless it's from someone I know who has my blood type and know they haven't been vaxxed. Don't trust hospitals or the people who work with the blood donations to not try to slip in some vaxxed blood. Your chances are not good that they would actually give you unvaxxed blood, because they don't mark the blood if the person has been vaxxed or not. Truthfully, I'd rather die than get vaxxed blood.
