In Vietnam, health care workers are learning to ask the right questions instead of making assumptions — and parents are responding by choosing to vaccinate their children. The insight comes from a groundbreaking study of the Vaccine Champions program, which trained community leaders and health workers to have better conversations about vaccines with hesitant parents.
The discovery reshapes how the world thinks about vaccine hesitancy. It turns out that most parents who delay or decline vaccines aren't ideologically opposed to vaccination at all. Rather, they're driven by a fundamental desire to protect their children from harm — and safety concerns are the biggest barrier they face. This distinction matters enormously, because it means the problem isn't changed minds, but better communication.
A clinical practice review by Murdoch Children's Research Institute Professor Margie Danchin and University of Colorado Anschutz School of Medicine Associate Professor Sean O'Leary, published in the New England Journal of Medicine, documented decades of evidence showing that routine childhood vaccines recommended by the American Academy of Pediatrics have dramatically reduced serious infectious diseases and maintain an overwhelmingly excellent safety record. The same proven results have been produced by Australia's National Immunisation Program.
What makes vaccines spread isn't facts alone — it's trust. Health professionals like GPs, immunization nurses, and pharmacists remain the most trusted source of vaccine information for parents, and clear, confident recommendations from these clinicians are strongly associated with higher vaccine uptake. But the way clinicians communicate matters profoundly. Presumptive approaches, which present vaccination as the expected norm, proved more effective than open-ended discussions. Crucially, when parental concerns were met with respectful, two-way dialogue rather than dismissal, vaccine confidence grew.
The Vaccine Champions program, supported by the Australian government and UNICEF, trained health care workers and community leaders using these principles. A study published in the Annals of Global Health examined the program's rollout in Vietnam, where it was co-designed with the Vietnamese Ministry of Health. The results were striking: of those who attended the education sessions, 86 percent reported an increased intention to vaccinate. Participants also reported high satisfaction with the sessions and materials.
What's remarkable is what happened next. The vaccine champions in Vietnam didn't stop when the initial program ended. They continued running education sessions on their own, and the Ministry of Health now uses them to support other public health priorities including nutrition and maternal and child health. The program proved so effective at building community trust that it became self-sustaining.
Belle Overmars, an MCRI researcher, emphasized the broader lesson: "A structured, multi-level model could strengthen vaccine confidence, empower local leaders and help reduce pressure on the health care workforce." That insight points toward a future where vaccine uptake improves not through confrontation or blame, but through empathy-based, patient-centered strategies that acknowledge parental concerns and build genuine trust. Professor Danchin noted that respecting communication and leaving the door open when vaccination is delayed or declined could influence future decisions and improve long-term immunization outcomes — a hopeful reminder that changing minds happens one respectful conversation at a time.
