Healthcare professionals need to proactively engage with pregnant women regarding maternal immunisation and collaborate in service delivery, according to a survey of individuals from the vaccination workforce. Interview participants (n = 6) were involved in education, certification and supporting vaccinators, high-level strategising, and vaccination. They noted that interventions must emphasise the importance of maternal immunisation, promote collaboration and innovation, make interventions accessible, and empower Māori- and Pacific-driven avenues to vaccination. Participants identified the importance of building and maintaining trust, and affording women time and autonomy in vaccination.
