Whichever variant(s) the southern hemisphere deals with is what the northern hemisphere's vaccine is made up of. It reverses for the southern when they head into winter.

As always, ACAB.

My tinfoil hat moment
What if Alberta goes through with this and it works? And what if the rest of Canada decides that we can do the same with the feds and Canada Post??
Then the US sees what can happen and has a nation-wide general strike and brings Trump et al to their knees????
Link doesn't work ... it's still loading.
TACO strikes again.
Don't forget there are different strains of the avian flu, so surviving one strain doesn't guarantee the bird would survive another.
Druggie buddy. :P
A little over 25 years ago I trained in Hamilton as a weather observor for NavCan. One of my fellow students was a meteorologist. He told us that big industries often recruited meteorologists out of university to provide wind and weather forcasts so the business would know when they could 'illegally' flare toxins through their stacks ... so they would know when the wind would keep the smoke away from gov't air monitors.
This shit has been going on forever.
Just oh-so-tired of being on the losing team. 😝

I just got the vaccine and am hoping it works. If not I've got lots of masks, including a half-face one. Those should hold me through the winter.
Fyi
washing your hands every time you're near a sink works wonders as well.
