At least 978,118 children have been vaccinated against Polio in Nairobi since January.
This is an increase from 600,000 that were vaccinated last year.
The County Health officers attributed the increase to massive community mobilization and awareness campaigns.
The county had targeted to vaccinate 883,822 children below five years.
Health executive Mohamed Dagane said health officers mostly targeted informal settlements, where there is dense population and high number of children.
“We had massive awareness campaigns targeting the informal settlements,” Dagane said.
Some of the areas that recorded high vaccination numbers include Pipeline, Kibra, Mathare, Huruma, Kasarani, Mukuru kwa Reuben, Kariobangi and Dandora.
The county involved over 6,000 Community Health Volunteers in the five-day exercise that kicked off on July 20.
The campaign was officially launched by Governor Mike Sonko who emphasized on the need for parents and guardians to ensure their children are vaccinated.
It was a door-to-door campaign with mobile teams visiting churches, mosques, temples and other religious centers in the city.
The vaccine was tested and qualified by the National Quality Control Laboratory.
The county deployed over 1,500 vaccination teams to help achieve the target.
During the vaccination exercise, the county realized the need to initiate more health oriented policies targeting informal settlements.
“We have to educate our people on the need to do consistent medical checkup,” Dagane said.
The County Government has been focusing more on revamping the health sector, with more resources being channeled for upgrade of county health facilities.
