2 types: There are two types of polio vaccines in the world. The oral type is a live-virus vaccine, but is no longer used in the U.S. Since domestic cases of polio no longer occur (because of the success of the oral polio vaccination program). We use the "inactivated" polio vaccine, which is not alive, and is given as a shot. The shot cannot cause polio disease.
