Fig 3. Probability that GBS maternal vaccination is cost-effective in each country under most favourable and least favourable normative assumptions (see Table 1).

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; GDPPC, GDP per capita; QALY, quality-adjusted life year; SB, stillbirth; SDG, Sustainable Development Goal.
