A quick fact check says that's not true;
"the inactivated poliovirus vaccine does not produce sterilizing immunity and is 90 percent or more effective. A vaccine can lessen the ability of a pathogen to produce a disease response without sterilizing it. If it does sterilize against a pathogen, it can prevent infection. For example, the human papillomavirus vaccine induces sterilizing immunity."
Duration of Protection
It is not known how long people who received IPV will be immune to poliovirus, but they are most likely protected for many years after a complete series of IPV.
