Polio health workers have been instructed by the Health Department of Punjab to take photographs of the children they administer vaccinations to, a spokesperson from the health department confirmed on Wednesday.

Health workers' teams will use Android phones to take photographs of children they administer the vaccine to. The photographs will be sent onto the Punjab Information Technology Board, the officials.

The move is to ensure better record-keeping of children who have been vaccinated, as well as to ensure that health workers are fulfilling their responsibilities, the officials said.

The development comes just days before a three-day polio drive is set to launch in Punjab on Oct 24.

Polio teams will visit areas in seven districts of Punjab, including Lahore, and administer the vaccine to children under five.

There are 4,500 polio vaccinations teams operating in Lahore alone.

The drive will be financed by donor agencies including Unicef, World Health Organization and the Bill Gates Foundation.

The teams from each Union Council will be overseen by the corresponding Union Council Medical Officer.
