A Safety Study For Prevenar 13 Among Chinese Children

Completed

Conditions: Seizures
Apnea
Fever
Urticaria and Angioedema

Registration Number: NCT03656939

Lead Sponsor: Pfizer

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

Detailed 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.

Recruitment & Eligibility

Inclusion Criteria

To be eligible for the main study, children in Yinzhou population-based EHR database must be aged 1 to 24 months and receive at least one dose of 13vPnC between May 1st, 2017 and July 24th, 2020 where the first dose is received before or on July 24th, 2020 since a 7-day post-vaccination follow-up for each dose in each child receiving 13vPnC is needed.
