The United States is the world's largest donor of COVID-19 vaccines, ahead of other major economies such as China, Japan and the United Kingdom, according to data compiled by UNICEF.

It is worth noting that UNICEF manages the supply of COVID-19 vaccines for the Kovacs Initiative, which aims to share doses with low-income countries.

On the other hand, Asian countries are among the largest recipients of COVID-19 vaccine donations, with Bangladesh, the Philippines, Indonesia and Pakistan receiving more than 10 million doses
