Gov. Greg Abbott issued an executive order Monday saying "no entity" could require employees or consumers to get the COVID jab.
It goes into effect immediately.
Abbott vows he's pro-vaccine and believes it's the best defense against COVID but wants it to be voluntary and "never forced."
The governor is also asking the Texas Legislature to pass a law banning vaccine mandates.
Multiple Texas hospitals, including Houston Methodist, fired workers for not getting the shot.
Dallas-based Southwest Airlines is also in a fight with its pilots union over vaccine requirements.
