That's correct. Not sure about the others, but Pfizer's vaccine comes in a vial containing 0.45ml of vaccine diluted with 1.8ml of saline solution, and that makes 6 doses of 0.3ml each (for those of you playing at home, yes that doesn't add up, that's to allow room for error. Better to have a dosage of more than 0.3ml than less. Also to allow for dead space within the syringe).
So yes, the vaccine is actually 75% saline.
