Abstract
Invasive meningococcal disease (IMD) is associated with a high mortality and severe sequelae. The aim of the present study was to evaluate the potential cost-effectiveness of the Bexsero vaccine in Brazil. We used a cohort model to compare routine vaccination against MenB disease with no vaccination. Epidemiological and cost estimates were obtained from the Brazilian Health Information System. The cost per disability-adjusted life year (DALY) averted and incremental cost-effectiveness ratio (ICER) was estimated assuming a 3-dose vaccination schedule, at R$90 (£ 20.50) per vaccine dose, 82.0% vaccine efficacy against MenB disease and a vaccine uptake of 90.0%. We estimated that 1,527 MenB cases would be prevented and 78 deaths averted. This strategy would cost R$ 762,381, 000 (£ 174,059,503) with a R$ 4,364,280 (£ 996,410) reduction in disease treatment costs. However, at an ICER of 372,256 (£ 84,990) per DALY averted, a vaccination programme is unlikely to be cost-effective.
