Relatively little is known about the differential impact of maternal and paternal perceptions of vaccine safety on children's vaccination status in New Zealand. Using a sample of 68 couples from the New Zealand Attitudes and Values Study (NZAVS), the present study investigated the distinct influence of mothers' and fathers' confidence in the safety of childhood vaccinations following the national immunisation schedule on their reports of children's vaccination status. Actor-Partner Interdependence Modelling revealed that mothers', but not fathers', vaccine confidence predicted children's vaccination status, regardless of who reported their children's vaccination status. Higher maternal vaccine confidence increased the likelihood of child full vaccination status, but paternal vaccine confidence showed no unique significant effects. As women tend to express lower vaccine confidence than men, it is imperative to further investigate the key drivers of their low confidence and develop target interventions accordingly. Encouraging fathers' involvement in the vaccination decision-making process may also be beneficial in increasing the likelihood of childhood vaccination uptake.
