The economic value of increasing geospatial access to tetanus toxoid immunization in Mozambique

•Tetanus is a leading cause of maternal and neonatal morbidity and mortality in LMICs.•Ensuring geographic access to tetanus toxoid (TT) immunization is vital.•We used SIGMA to quantify geographic access to TT and disease impact in Mozambique.•People must travel up to 35km for 99% of the population to reach health centers.•TT can prevent significant disease burden and costs if geographic access is improved.
