Pakistan is one of the few countries in the world still affected by the polio virus.

Now, in an unusual effort to eliminate the disease, health workers are stopping vehicles at a busy toll booth outside Islamabad to administer free polio vaccination drops to children under the age of five.

The government hopes to eradicate the virus by the end of the year, but many people do not believe that they will reach this target.
