The equity road ahead for financing non-national immunization program vaccines in China: challenges and opportunities from a qualitative study.

BACKGROUND

In China, national immunization program (NIP) vaccines benefit from robust financial support and have achieved high coverage. Non-NIP vaccines rely on fragmented funding sources, mostly out-of-pocket payment, and face sub-optimal and inequitable coverage. Sustainable financing needs to be secured for addressing equity in non-NIP vaccine delivery. However, discussion and understanding of this issue remain limited. This study aims to analyze the current situation, comprehensively identify challenges and opportunities in non-NIP vaccine financing, and offer suggestions to enhance vaccine uptake and improve public health.

METHODS

Between July and December 2023, we conducted a series of semi-structured, in-person interviews with 55 stakeholders from the Health Bureau, Centers for Disease Control and Prevention, Medical Insurance Bureau, and Finance Bureau across five provinces in China. Participants were selected through stratified sampling, and the interviews mainly included their involvement in non-NIP vaccine financing, challenges faced, and strategies for improvement to enhance financing performance. Informed consent was obtained, and thematic analysis was used to analyze the data.

RESULTS

Non-NIP vaccine financing sources include out-of-pocket payments, government fiscal, health insurance and other external funds. These four channels differ in vaccine types covered, costs, and target populations, each with unique challenges and opportunities. High out-of-pocket costs remain a significant barrier to equitable vaccine uptake, while market competition has lowered the vaccine price and improved accessibility. Local fiscal support for free vaccination programs faces challenges related to sustainability and regional disparity, though governmental commitment to vaccination is growing. Nevertheless, centralized procurement organized by the government has lowered the price and reduced the financial burden. Despite legal restrictions on using basic health insurance for vaccinations and limited commercial insurance options, private medical savings accounts and mutual-aid mechanisms present new opportunities. Although the scope and impact of external support are limited, it has successfully increased awareness and social attention to vaccination.

CONCLUSION

Relying on individual payments as the main financing channel for non-NIP vaccines is unsustainable and inadequate for ensuring universal vaccine access. A concerted and synergistic approach is essential to ensure sufficient, sustainable resources and enhance public financial management to improve equity in the non-NIP vaccines.
