Vaccination is among the most effective ways to avoid mortality and morbidity from vaccine-preventable diseases. Its ability to provide collective protection, however, depends on high vaccine coverage (VC) rates (≥ 95%), which many countries do not reach [The motivational interview (MI) [To determine whether these results could be attained in the French context, we conducted a randomised controlled trial (RCT) from November 2021 to April 2022 in two maternity wards in south-eastern France. The primary objective was to provide evidence that, given the French setting of childhood vaccination requirements expansion, a post-partum educational strategy based on MI offered to mothers can significantly reduce their VH and increase their intentions to have their child vaccinated, compared with standard care. Two secondary objectives were to (i) test the differential impact of MI on VH and VI according to social status and (ii) evaluate mothers’ acceptance of and satisfaction with this approach.
