President Joe Biden plans to buy and donate 500 million doses of the Pfizer coronavirus vaccine to more than 90 countries, while calling on the world’s democracies to do their part to help end the deadly pandemic.

The announcement of the vaccine donation — the largest ever by a single country — comes ahead of Biden’s meeting with leaders of the other Group of Seven advanced economies — Britain, Canada, France, Germany, Italy, and Japan — in Cornwall, England.
