Fig 5. Distribution of GBS vaccine threshold prices among countries within each World Bank income group under most and least favourable normative assumptions (see Table 1).

Threshold vaccine prices above $800 per dose are not shown. Least favourable normative assumptions were the use of an empirical CET, 3% discounting of QALYs, and exclusion of stillbirth QALYs. Most favourable assumptions were the use of 1 × GDP per capita CETs, 0% discounting of QALYs, and inclusion of stillbirth QALYs. CET, cost-effectiveness threshold; GBS, Group B Streptococcus; GDP, Gross Domestic Product; QALY, quality-adjusted life year.
