The U.S. is looking to “loan” a total of 4 million doses of the AstraZeneca vaccine to Canada and Mexico.

The White House press secretary Jen Psaki who confirmed this development on Thursday also disclosed that at least 2.5 million will be loaned to Mexico and 1.5 to Canada.

Psaki has given an update concerning the vaccine in the U.S. It has 7 million “releasable” doses of the vaccine, which is yet to be approved by the U.S. Food and Drug Administration but has been approved by other countries.

According to CBS, In the past, Psaki has responded to questions about why the U.S. is holding onto the AstraZeneca vaccine doses by saying the Biden administration is prioritizing vaccinating Americans.

Psaki who spoke further on the pandemic said; it “knows no borders”, stressing that apart from Europe Canada and Mexico are not the only countries that have requested the United States’ AstraZeneca doses.

On the loan, Psaki spoke to reporters during the White House briefing made comments.

In his words, “We are assessing how we can loan doses,” It’s not fully finalized yet, but that is our aim and what we’re working toward, to Canada and Mexico. This is a complex process and our team is working with the companies to move it forward.

“And I want to, on your question about the number of doses, there have been a range of reports about the number of doses. I can confirm that we have 7 million releasable doses available of AstraZeneca, and … 2.5 Million of those we are working to finalize plans to lend those to Mexico, and 1.5 million to Canada.”

Psaki said the loan could be repaid with future AstraZeneca doses or potentially “other” doses. AstraZeneca is a British-Swedish pharmaceutical and biotech company that is headquartered in England.
