How much will it cost different low- and middle- income countries (LMICs) to provide COVID-19 vaccine to their population?
An interactive application to explore and predict COVID-19 vaccination cost.
Successful control of COVID-19 pandemic not only depends on the research and development of effective vaccines, but also on delivery of these vaccines to everyone. Therefore, for any country the total cost–procurement plus delivery cost– to vaccinate its population is a crucial information as this can help the country to plan, raise, and allocate resources needed to successfully vaccinate their population against the COVID-19 pandemic. This information becomes even more important and pressing for low- and middle- income countries (LMICs) which are already under enormous financial stress due to the impact of COVID-19 on their economies. Therefore, I, along with my colleagues at The center for policy impact in global health developed an application where one can obtain, and predict the total cost COVID-19 vaccination for 117 LMICs.
We provide vaccination cost to reach herd immunity in a country i.e. cost to vaccinate 70% of the population, cost to vaccinate high-risk population such as population with comorbidity, and cost to vaccinate health professionals. The baseline data, and information on the methodology used for calculating the costs can be found on page 3 and page 4 of the application.
However, a general user or a policymaker might want to input their own data as they might have more accurate information for certain variables used for cost calculations in this application. Therefore, to accommodate such scenarios, we have provided the option to the users to input their own data for the variables used for vaccination cost calculation, and get the new vaccination cost information based on the user input.
Through this post, i would like to provide more information about this application, and how a user can interact and extract the maximum information from the application.
Page 1: “COVID-19 Vaccination Cost Map” The first page of the application shows the distribution of different vaccination costs– 70% population, high-risk population, and health professionals. These costs are based on our calculation using the baseline data. The baseline data can be found in the “Data Explorer” tab. A user can choose vaccination cost for different population segments, and then can click on a country of their choice to view the total cost to vaccinate its population on the chart in the panel on the right. In addition, there is an option in the panel named “Include COVAX procurement pricing”. If a user does not check this option, the vaccination cost for COVAX-AMC eligible countries will use USD5.25 as the median vaccine procurement cost (more information on the median cost can be found in the methodology section of “About this site”). However, if “Include COVAX procurement pricing” is checked then the vaccination cost for COVAX-AMC eligible countries will use the COVAX pricing i.e USD3. The countries which are not COVAX-AMC eligible will continue using the median vaccine procurement cost of USD5.25 in the cost calculations.
Page 2: “Scenario Analysis and Immunization Comparison”
After you have explored the baseline calculation of total costs, but would like to obtain granular information like how much does it cost for a country to procure the vaccine, or how much will it cost to deliver the vaccine to its population, you can move to
Scenario Analysis and Immunization Comparison tab. This tab provides user the ability to visualize costs for various scenarios. For example, a country might only incur vaccine procurement costs, and the delivery cost for such a country was being covered by some international organization or a bilateral donor, or there could be a scenario that vaccine procurement cost might have been take care off for a country by some donor, but the country will still incur delivery cost to vaccinate its population, and finally there could be the usual situation when the country incurs both the vaccine procurement and delivery cost. This page of the application provides option to a user to choose any of these scenarios for the country of their choice and visualize the vaccine procurement, delivery and total cost for 70% population, high-risk, population, and health professions. Similar to the first tab a user can again check “Include COVAX procurement pricing” if they want to include COVAX pricing in the cost calculation for their country of choice.
In this tab, we also provide user the option to input their data to obtain the vaccination cost for different countries. Users can input their data for the variables on number of health professionals, high-risk population, number of doses, bilateral vaccine procurement cost, and vaccine delivery cost by clicking on
Click to input your data! button. Based on the user input the chart and the table below the chart will update.
In addition to vaccination costs, the charts also plots the immunization costs incurred by a country (most recent available data is plotted). A user can make comparison between the incurred immunization cost, and required COVID-19 vaccination cost for any country.
Page 3: “Data Explorer” This page provides the baseline data used for the cost calculation in this application. The baseline data includes information about country’s COVAX eligibility, number of health professionals, immunization cost, total population, high-risk population percent, population covered by COVAX, population covered by bilateral deals, number of doses, vaccine procurement costs (bilateral and COVAX), and vaccine delivery cost.
