I'm in the states, and they consider 2 dose to be "fully vaccinated". This is relevant for all laws that mention the requirement is to be "fully vaccinated", and that's 2 dose for Pfizer or Moderna and one for J&J.
If you have been vaccinated in Canada with AstraZeneca you are not considered vaccinated at all in the US (not approved) and you might or might not be considered vaccinated in Europe depending on the manufacturer/lot of your shots (UK, vaxzevria, yes, India, covishield, no, USA, just called AstraZeneca, cannot find any information about it) and the European country in question (not all countries accept all AZ manufacturers as valid).
It is a fairly ridiculous situation and if you need to travel it's definitely an issue given a lot of countries are moving towards "green pass" type actions where unless you are "fully vaccinated" (with the approved vaccine) life will be very difficult for you.
There really should be a better solution about at least the most common vaccines being cross recognized everywhere and not used to artificially block people from moving (why should AZ manufactured in the UK be treated any differently from AZ manufactured in India)
The problem is that the United States is relying on FDA approval for its recognized vaccines. As a result, AZ shots are not recognized for US-travel purposes, so a Canadian who received a first AZ shot and a second Pfizer shot has only one dose as far as the US is concerned.
Canada has approved the J&J vaccine, but it has not distributed any such shots. The first shipment it received came from the troubled production facility that operated off-spec, and the shipment was ultimately rejected (https://www.nytimes.com/2021/06/12/world/canada-jj-vaccine.h...). Canada has only distributed AZ, Pfizer, and Moderna shots.
