Here we will describe the development of the programme following the first four of the six IM steps as shown in Figure 1, including the application of these steps for our study aim.

IM Step 1: Logic model of the problem
As the initial step of the IM process, we started forming a planning group with relevant stakeholders. We invited members of three groups of HCWs who provide close and frequent care for young infants in the Netherlands, and therefore pose the greatest risk of transmitting pertussis to infants: maternity assistants (who care for mother and child at their home after delivery), midwives (who assists women in childbirth) and paediatric nurses (who care for children admitted to a hospital). At the time, it was clear that at least these professionals would be included in the policy advice that had to be issued by the Health Council of the Netherlands. Furthermore, we recruited members with exper tise on vaccination acceptance, implementation development, and behavioural science, and members who would be involved in decision making on the regional implementation of the vaccination programme. Some members had multiple roles. In total the planning group consisted of 11 members, including the research team (OV, JH, MH, RR, KV).
Subsequently, we constructed a logic model of the problem, answering central questions as “what is the problem?”, and “for who is this a problem?” (see Figure 2). The at
