Popis: | BACKGROUND: Currently, there are no solutions to prevent congenital transmission of Chagas disease during pregnancy, which affects 1–40% of pregnant women in Latin America and is associated with a 5% transmission risk. With therapeutic vaccines under development, now is the right time to determine the economic value of such a vaccine to prevent congenital transmission. METHODS: We developed a computational decision model that represented the clinical outcomes and diagnostic testing strategies for an infant born to a Chagas-positive woman in Mexico and evaluated the impact of vaccination. RESULTS: Compared to no vaccination, a 25% efficacious vaccine averted 125 [95% uncertainty interval (UI): 122–128] congenital cases, 1.9 (95% UI: 1.6–2.2) infant deaths, and 78 (95% UI: 66–91) DALYs per 10,000 infected pregnant women; a 50% efficacious vaccine averted 251 (95% UI: 248–254) cases, 3.8 (95% UI: 3.6–4.2) deaths, and 160 (95% UI: 148–171) DALYs; and a 75% efficacious vaccine averted 376 (95% UI: 374–378) cases, 5.8 (95% UI: 5.5–6.1) deaths, and 238 (95% UI: 227–249) DALYs. A 25% efficacious vaccine was cost-effective (incremental cost-effectiveness ratio |
