More than half of parents whose children are partially vaccinated believe vaccines are “unsafe,” according to a 2025 survey conducted by Australia’s National Centre for Immunisation Research and Surveillance (NCIRS).
Lack of trust in vaccine information from doctors and nurses, and not prioritising vaccination over other things were also barriers to vaccine uptake among the same cohort, the survey of 2,012 parents of children under 5 years of age found.
