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.
According to official data, Kenya launched the vaccination campaign targeting children under five years of age following an outbreak of the disease in Garissa County.
The WHO noted that Kenya, with other countries in the Horn of Africa, remains at risk of imported wild poliovirus from neighboring Somalia.
Official data shows that Polio is a debilitating and incurable disease that predominantly affects children below the age of seven.
In Kenya, the second and third rounds of polio vaccination will be carried out in September and October, the WHO said.
