The International Monetary Fund says about $50 billion may be all it takes to vaccinate all eligible people around the world by the middle of next year. The IMF has proposed an investment programme that could have a global economic benefit of around $9 trillion.
The detailed research piece prepared by the IMF Chief Economist Gita Gopinath and colleague Ruchir Agarwal suggests that the goal is to vaccinate 40% of all countries by 2021 and the remaining 60% by the first half of 2022.
The benefit to developed countries - which would have to fund a great deal of this - would be to the tune of $1 trillion in additional tax revenue apart from 40% of the cumulative $9 trillion in global GDP gains. The proposal's total cost of around $50 billion would include grants, national government resources, and concessional financing.
