I've thought this, I've had both my vaccines. I guess it's because many countries don't have any "vaccination passport" program to prove you've been vaccinated. I know here in the U.K there's no way for me to prove I've had the vaccine. They'd need access to my medical records somehow and I guess that's a tricky thing to get ahold of from different countries around the world.I don’t know why IRCC isn't adding fully vaccinated outland applicants under the travel exemptions. I have UAE residence and vaccination is now widely available for all adults.
