Questions	Reopening
First ice breaking question: we are going to talk about regular changes of the vaccination schedule. At first, could you tell us how do you use the vaccination schedule in your daily practice?	Regarding the children/infants? How do you explain it to the parents
Why do you face some difficulties?	How do you resolve any possible conflicts or misunderstandings?
Do these changes seem justified to you?	How would you explain these changes? Why would it be a problem?
In order to make the current vaccination schedule easier, a work group of the French Technical Vaccination Committee would possibly reduce the number of injections administered to infants from 4 to 3 injections between 0 and 18 months of DT-IPV-Ca-Hib¥. This would imply an important modification of the actual vaccination schedule.
How, in terms of acceptability, usefulness, feasibility, and impact on practices, would you react to such a change?	Would you need more scientific evidence?
Do you think that this change will be understood or accepted by the family of the children involved (a priori and/or based on past experience)?	What level of proof do you need a priori?
How do you plan to apply these changes?	Would you be willing to incorporate this change into your practice? What would be your condition(s) to apply? If you are not ready or disagree, why?
What are your wishes for the implementation of the revised schedule?	If such a change took place, what are the best ways for you to set it up?
What do you think of the current means to broadcast new recommendations?	What tools would you like to get in order to make access to information easy about the foreseen change?
	What tools are currently available to you? Which ones do you use?
Compared to those you already have, do you think they should be improved? Multiplied?
