Typhoid conjugate vaccine (TCV) is likely to be cost-effective in countries with high typhoid incidence, high cost of typhoid treatment, and/or high death rates from typhoid. Below, explore the predicted vaccine impact and cost-effectiveness for 54 Gavi-eligible countries.

Predicted impact 10 years after introducing TCV
Minimum price a decision-maker needs to be willing-to-pay for a unit health gain for vaccination to become preferred over no vaccination in terms of cost-effectiveness.
For each of the 54 Gavi-eligible countries, this chart shows the lowest price a decision-maker needs to be willing-to-pay for one disability-adjusted life-year (DALY) averted, thanks to vaccination, at which any of the three TCV vaccination strategies becomes preferred compared to no vaccination, in terms of cost-effectiveness.
If the decision-maker’s willingness-to-pay threshold is greater than or equal to this value, then TCV vaccination is considered cost-effective. Each country should establish its own threshold based on local preferences.
Lowest cost per DALY averted at which vaccination is more cost-effective than no vaccination (in USD2016)
Dividing the cost per DALY averted by each country's gross domestic product (GDP) per capita gives a value to determine whether the intervention is cost-effective or not.
