Prime Minister Justin Trudeau said today his government is working with the U.S. and other international partners to ensure that AstraZeneca vaccine recipients face few barriers when they travel abroad.

Trudeau’s commitment comes at a time when some U.S. venues are already suggesting they will only allow people who’ve been fully vaccinated with a United States Food and Drug Administration-approved product — the Pfizer-BioNTech, Moderna or Johnson & Johnson vaccines — to attend certain events unencumbered.

While AstraZeneca shots are made at some U.S. facilities, the FDA has never approved it for use in the American marketplace.
