【Abstract】 Objective To monitor the change of parental confidence in vaccination in selected provinces following the Shandong Illegal Vaccine Selling Event,and to provide evidence for improving strategies of vaccination utilization and communication. Methods At least 100 parents of children aged 0-23 months were randomly selected from each of 22 counties,which had been randomly selected from 11 provinces.We conducted telephone interviews of these parents from March 26 to April 6,2016 and from May 12 to May 25,2016. Results 2 340 and 2 204 parents were interviewed in the first and second surveys,respectively. In both surveys, > 80% of parents knew of the event; about 70% parents learned about the event from the Internet; about 40% believed that the involved vaccines were poisonous; about 60% believed that the involved vaccines were harmful to health; and 50% believed that the involved vaccines were not effective. In urban areas,the proportion of parents believing that vaccines were safe increased from 31. 13% in the first survey to 39. 11% in the second survey( χ2= 66. 99,P < 0. 001),and in rural areas,the proportion increased from 37. 03% to46. 22%( χ2= 42. 89, P < 0. 001). The proportion of parents refusing Category II vaccines declined from 49. 05% to 39. 25% between the 2surveys. The proportion of parents hesitant to use Category I vaccines declined from 23. 69% to20. 25%. The proportion of parents refusing Category I vaccines dropped from 12. 35% to 7. 53%.Conclusions The event caused a wide impact on parental confidence on immunization,and parental confidence was regained gradually and incompletely.
