Warrap State Tonj Civil Hospital will on Friday train Polio, Measles vaccinators to reach more vulnerable people.
Officer William Marial urged parents, guardians and chiefs to allow their children get vaccination to fight against diseases in the country, Don Bosco Radio reported.
He said vaccinators fear to reach other areas like Atermony and Cuwejai because of insecurity but they would visit all the areas to prevent children from the killer diseases.
Mr Maril advised areas that vaccinators were not reaching to be patient.
