Why is the oral polio vaccine better than another form?

See below:: Opv is better at stopping the spread of the virus to others, but now that wild (natural) polio has been eliminated from the western hemisphere, this advantage is no longer a consideration in the United States. Ipv has been used exclusively in the United States since 2000. However, in other countries where wild polio is still a threat, OPV is still used.

Indirect effect: The oral vaccine virus is excreted in the stool of the recipient and helps inoculate some that do not receive the vaccine directly by indirect exposure. The enhanced killed vaccine we use in the US was adopted primarily because of the 2-3 cases of OPV related polio we had/yr in immune compromised kids.Our vaccine is quite effective and has no risk of producing a polio like illness.

Is it?: For the most part, there is no difference but the usa stopped using the oral vaccine because there was no polio except that caused by the oral vaccine.
