The district health department kicked-off its three-day special migratory pulse polio campaign here on Sunday. Under this campaign, the department will administer polio drops to children of migratory labourers, in the age group of 0-5 years.
On day one, the department, through a door-to-door campaign, administered the vaccine to around 12,000 children.
Patiala civil surgeon Dr HS Bal said the department had achieved the target of administering the vaccine to 50% of the eligible children.
He said: "A total of 168 teams have been constituted by the health department to administer the vaccine to children of migratory labourers living in slums, industrial areas and newly constructed buildings, and working in grain markets."
Bali also visited several areas in the district on Sunday to oversee the campaign. District vaccination officer Dr Narinder Kaur, who supervised the campaign, said along with 168 teams, about 14 mobile teams had also been constituted to administer the vaccine.
Kaur added: "About 19 supervisors have also been deployed to keep a tab on the progress of the campaign.
