According to official reports, the five-day polio campaign was held in the capital of Nairobi, the neighboring Kiambu and Kajiado counties, as well as Garissa in the northeast region and targeted 1.8 million children.
"About a million children were vaccinated in Nairobi, 287,000 in Garissa, 240,000 in Kajiado and over 334,000 in Kiambu," the WHO, which carried out the campaign in collaboration with Kenya's Ministry of Health, said in a statement issued in Nairobi.
"The drive involved hundreds of health workers moving from house to house and some in harsh conditions. Most parents availed their children," the WHO said.
