Once the FDA approves the Astra-Zeneca vaccine, the U.S. Government will donate 60 million doses worldwide at no cost. We had originally contracted for 300 million doses but with the supply of Moderna, Pfizer and J & J vaccines, the AZ vaccine won't be needed in the US.
There is no word as to where the vaccines will go but Canada and Mexico have requested more be sent to them.
The more people vaccinated the safer it will be to travel.
