Canadians who work and or reside(temporarily even) are eligible for the shot in Washington State. Didn’t read your article yet but I assumed there would/could be issues with Canadians getting partially or fully vaxxed abroad sooner or later.Washington State isn't mentioned....interestingly.
Additionally, many Canadians and Snowbirds are running into issues in registering their US vaccinations and this could be problematic should Canada go with covid passports: https://bc.ctvnews.ca/travellers-re...t-of-province-covid-19-vaccinations-1.5458182
Also in fully vaccinated news:https://www.bloomberg.com/news/arti...lax-quarantine-rules-for-vaccinated-travelers
Looking forward to more details.
