On Thursday, Biden is expected to announce that he has reached an agreement with Pfizer and BioNTech to provide 500 million doses of coronavirus vaccine to about 100 mostly low-income countries over the next year.

In an effort to get the world vaccinated and reduce the disparity in vaccination rates between rich and poor nations, the US is pitching in.

Reportedly, the US will offer the doses at a “not-for-profit” price. The first 200 million doses would be distributed this year, and 300 million by the middle of next year.

As Biden stated in an address to American troops after landing in England:

“We have to end Covid-19, not just at home, which we’re doing, but everywhere. There’s no wall high enough to keep us safe from this pandemic or the next biological threat we face, and there will be others. That requires coordinated multilateral action.”

Though 500 million doses is a good start, the World Health Organization estimates 11 BILLION are needed to vaccinate the world.
