Polio Vaccinator Is Shot and Killed in Pakistan

Two gunmen on motorcycle shot and killed a polio vaccinator in the southwestern Pakistani city of Chaman on Thursday, bringing the death toll among vaccinators working in the country’s anti-polio drive to at least three this week, officials said.

Polio vaccination teams have suffered several attacks since a countrywide vaccination drive began on April 23.

Polio workers, volunteers and their guards are frequently targeted in the South Asian country. 

Islamist militants and hard-line clerics say the vaccination drive is a foreign plot to sterilize Muslim children and a cover for western spies.

Hayat Khan, a resident of a tribal area bordering Afghanistan who runs a shop, said he is skeptical of the polio vaccine. 

Neither he nor his parents have taken the vaccine, which can be delivered orally as drops, and they are living a healthy life, he said.

“We have doubts in our minds about this western vaccine,” he said. 

“Tribal people are not sure what they are giving to our children and what information they are collecting for spying. It’s a Western agenda, indeed.”
