A polio vaccination campaign began Monday in 33 provinces of the country.

During this four-day campaign, eleven million children will receive vaccinations, according to Sharafat Zaman Amarkhil, a spokesman for the Ministry of Public Health.

"Our aim in this campaign is to apply the vaccine to eleven million children. This campaign will last for four days. Vitamin A tablets are also given to children under the age of five at the same time as the polio vaccination,” the spokesman said.
