The White House said it was finalizing plans to send a total of 4 million vaccines to neighbors Canada and Mexico on Thursday, in the country's first exports of shots.
Of those doses of the AstraZeneca COVID vaccine, about 2.5 million will go to Mexico while 1.5 are flagged for Canada as a "loan."
"Our first priority remains vaccinating the US population," said White House press secretary Jen Psaki. But she said, "ensuring our neighbors can contain the virus is a mission critical step, is mission critical to ending the pandemic."
Also on Thursday, US President Joe Biden praised the progress with his country's vaccine rollout, saying the US is on track to administer 100 million vaccine doses in his first 100 days in office.
"I'm proud to announce that tomorrow, 58 days into our administration, we will have met our goal," said Biden, nothing that the milestone dose will likely be administered on Friday.
He added that 65% of Americans who are 65-years-old or older have received at least one dose of a vaccine.
The European Medicines Agency (EMA), the European Union agency that evaluates medicine, said the AstraZeneca COVID-19 vaccine was safe.
The head of the EMA, Emer Cooke, said, "if it were me, I would be vaccinated tomorrow." However, she said she "still cannot rule out definitively a link" between rare types of blood clots and the vaccine. For more on the story, check out our reporting here.
European Commission President Ursula von der Leyen said the EU would not hesitate to restrict exports of COVID-19 vaccines in order to receive the doses that it was promised.

"Open roads run in both directions," said von der Leyen. "We want to see reciprocity and proportionality in exports, and we are ready to use whatever tool we need to deliver on that."
While she did not mention any countries directly, the comments appeared at least partly aimed at the UK, which recently left the EU and where the AstraZeneca development process was spearheaded.
