Inactivated Polio Vaccine (IPV): Developed by Jonas Salk, it has been in use since 1955; this vaccine consists of a dose of killed virus. Administered in three to four doses, it requires injections. Its cost would be of several dollars a dose, however it is available at $1 a dose in many countries
Oral Polio Vaccine (OPV): The OPV was developed by Albert Sabin and has been in use since 1960. It consists of a weakened (attenuated) version of the polio virus, administered orally in three to four doses, through drops. It costs $0.12 to $0.15 and since it doesn’t require injections, untrained personnel can deliver it easily and safely
