1. Study identification
EU PAS Register NumberEUPAS13766
Official titleTesting new approaches to monitoring benefit/risk with pertussis vaccines as test case: Incidence rates of pertussis and pertussis related outcomes of whole-cell pertussis and acellular pertussis vaccines in pre-school children
Study title acronymbenefit study on pertussis vaccinatoin
Study typeObservational study
Brief description of the studyThe overall proof-of-concept (POC) question is to test the system for benefit-risk monitoring of vaccines in Europe. This will first be done by using test cases. For this POC, the following research question is used: “Has the initial benefit-risk profile in children prior to school-entry booster been maintained after the switch from whole-cell pertussis vaccines to acellular pertussis vaccines”?
There will we 3 different POCs carried out, the one presented here will test the benefits of pertussis vaccines in the population.

11. Scope of the study
What is the scope of the study?
Disease epidemiology
Risk assessment
Primary scope : Risk assessment
12. Main objective(s)
What is the main objective of the study?
The objective of the work of the benefit pillar is to calculate incidence rates that will feed into the benefit/risk model (benefit-risk protocol).
Are there primary outcomes?Yes
pertussis is the primary outcome
Are there secondary outcomes?Yes
Secondary outcomes are complications to pertussis, such as pneumonia and seizure and death.
13. Study design
What is the design of the study?
Cohort study
14. Follow-up of patients
Will patients be followed up?Not applicable/no follow-up
15. Data analysis plan
Please provide a brief summary of the analysis method
The incidence rate of each event will be calculated using a dynamic cohort approach. When analyzing the incidence of pertussis, for each person in the cohort, follow-up time will be classified by calendar year, sex, age in months and the different risk window (see exposure section). This persontime will be the denominator for the incidence rate calculations. Incidence rates for the different outcomes will be calculated stratified by:
1. database
2. calendar year and month
3. age in categories
4. vaccination status by risk window stated above
5. pertussis prior to first dose
