• Numerator: Number of low- and middle-income countries among WHO Member States whose share of national immunization schedule vaccine expenditure funded by domestic government resources increased or remained stable compared to previous year.
• Denominator: Number of low- and middle-income countries among WHO Member States with relevant data from 2018 until the most recent reporting year.

Step 1) Retreive relevant data from WHO estimates of expenditures on vaccine.

Step 2) Calculate the share of national immunization schedule vaccine expenditure funded by domestic govrnment for low- and middle-income WHO Member States (based on the 2019 World Bank classification).

Step 3) Limit analysis to countries that have complete data available from 2018 through the most recent reporting year.

Step 4) Calculate the share of national immunization schedule vaccine expenditure funded by domestic government and round to the nearest whole number.

Step 5) Calculate the percent change in the share calculated in the previous step (e.g., 2018-2019, 2019-2020, etc.).

Step 6) Categorize into Increased, Stable, or Declined based on the percent change (“Stable” is defined as 0% change between the two consecutive years).

ccine expenditures, but expenditures related to doses of vaccine given through supplemental immunization activities (SIAs) are excluded.
