Clinical Trial Summary

This is an observational study based on a population-based EHR database.

Description:

This observational study based on a population-based EHR database in Yinzhou district of Ningbo city in China is to estimate incidence rates of seizures (including febrile seizures), urticaria and angioedema, apnea, and fever among Chinese children after receiving Prevenar 13. In addition, a validation study including validation of International classification of diseases, tenth revision (ICD-10) codes or ICD-10 code based algorithm for identifying all safety outcomes of interest and a prospective cohort study in a sub-population of the main study will be conducted in order to offset the potential biased results from the main study because of potential misclassification of the safety outcomes of interest due to miscoding and/or undercoding of ICD-10 codes used to identify these safety outcomes in the EHR database.
