:Oral Polio Vaccine (OPV)--this vaccine makes use of a live-attenuated form of the virus. It is administered orally, infects the host, and is spread in the same way as polio. It does not cause paralytic polio. One advantage of this vaccine is that it can "passively" vaccinate those who do not get vaccinated normally. Unfortunately, immunocompromised people can become quite ill from exposure, so this vaccine is largely being replaced in the US.

:Inactivated polio vaccine (IPV)--this is an injected vaccine that is now widely used in the US.

A common vaccine for Polio is IPOL, which is grown in cultures of Vero monkey kidney cells, according to Aventis Pasteur, its manufacturer. This poio innoculation has generally replaced the vaccine, Poliovax, manufactured by Sanofi Pasteur, which was produced from the cell line of an aborted fetal tissue, known as MRC-5.
