Of course we already knew this, but it’s a simple message.
If the bans were effective, they would be happy to share the evidence.
Since they refuse to provide data it’s obvious they have nothing to do with health.
If they wish to correct the record they can provide the studies.
Why do I need to link to it? why don't you just type "Canada unvaccinated travel ban" or something similar into google?
I'm more comfortable responding to something that has some basis in truth. There are too many people who only have the voices in their heads for support.
