Wanaparthy: District collector Adarsh Surabhi appealed everyone to cooperate in building a polio-free society by ensuring that all children receive Pulse Polio drops and make the campaign a success. He inaugurated the Pulse Polio immunisation campaign at the Mother and Child Health Centre here on Sunday. The collector administered polio drops to several children. Surabhi said every child upto the age of 5 years in the district would be given Pulse Polio drops. Around 46,000 children across the district would receive polio drops through 343 Pulse Polio booths. If any child misses receiving the drops at the booths for any reason, health workers will visit homes to identify such children and administer the vaccine. He urged parents to ensure that no child under five years is left out; every eligible child receives the polio drops. Parents whose children could not receive the drops are to contact their local ASHA worker so that they can be vaccinated without delay.
