OBJECTIVES: To evaluate the budget impact and cost-effectiveness of dengue vaccination following pre-vaccination serological screening in India.
METHODS: We used a static cohort model (combination of decision tree and Markov model) to compare dengue disease and cost burden with and without dengue vaccination program with serological screening for a hypothetical cohort of 10-year-old adolescents. Budget impact was expressed in terms of total budget required for implementation of vaccination programme. Program impact was expressed in terms of disability-adjusted life-years (DALYs) averted. Cost effectiveness was expressed as costs per DALY averted. All costs are expressed in 2018 US dollars. Sensitivity analysis was performed for ICERs in different vaccination scenarios.
RESULTS: The total budget for implementation of dengue vaccination programme is approximately around US$ 530 million (INR 3620 crores). Our model results suggest dengue vaccination result in a net gain of almost 86,000 DALYS. We found the Dengue vaccine to be a cost-effective intervention with an ICER of $3364 (INR 2,30,098) which is less than three-times GDP per capita of India ($6047; INR 413,601). One-way sensitivity analysis shows that the ICER is most affected by the overall incidence of dengue infections followed by vaccine price. Probabilistic sensitivity analysis shows that ICER for dengue vaccination varied from $1182 (INR 80,837) to $6367 (INR 435,439).
CONCLUSION: Our study shows that dengue vaccine with pre-vaccination serological screening programme is a cost-effective intervention with the conservative estimates.
