New Study Sheds Light on Reaching More Children with Vaccines in Lao PDR

Vientiane, 18 September 2025 - A new study led by the Faculty of Public Health at the University of Health Sciences, with support from UNICEF and Gavi, the Vaccine Alliance, provides fresh insights into how more children in Lao PDR can be reached with life-saving vaccines.

The mixed-methods study, conducted in Xaythany (Vientiane Capital), Dakcheung (Sekong), and Houn (Oudomxay), examined the experiences of caregivers, communities, and health providers to better understand barriers to immunization. Findings show that nearly 15 percent of surveyed children had not received their first dose of the Pentavalent vaccine before their first birthday.

The Ministry of Health welcomed the findings and reaffirmed its commitment to equitable immunization “Every child in Lao PDR deserves protection against preventable diseases. We are committed to working with partners to address the barriers revealed by this study and to reach the most disadvantaged communities,” said Dr. Vanphanom Sychareurn and Research team.

The study highlights both community and health system challenges: distance from health facilities, road conditions, and cultural practices that limit newborn mobility, as well as vaccine stockouts, irregular outreach, and communication gaps between health workers and caregivers. At the same time, it points to solutions including the central role of health worker trust, community volunteers, and village leaders in supporting families.

“This research provides a roadmap for action,” said Magali Romedenne, UNICEF Deputy Representative in Lao PDR. “By strengthening outreach, ensuring consistent vaccine supply, and supporting health workers to engage with families, Lao PDR can make sure every child benefits from the protection of vaccines.”

The recommendations emphasize equity-focused strategies aligned with Lao PDR’s national target of 95 percent immunization coverage and the global Immunization Agenda 2030.
