NMB of GBS maternal vaccination (A) globally under different normative assumptions (see Table 1) and (B) by region for the most and least favourable normative assumptions. 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. M, Millions; B, Billions; CET, cost-effectiveness threshold; GDP, Gross Domestic Product; GDPPC, GDP per capita; NMB, net monetary benefit; QALY, quality-adjusted life year; SB, stillbirth; SDG, Sustainable Development Goal.
