In a couple of different capacities, I work with international teams. I received an email - sent by a USian, a few weeks back that ended with the closing, "I hope you all are enjoying vaccinated life" and I cringed internally.
I am vaccinated. I am lucky to live somewhere, and to have had a schedule at the time that meant I could just pick the best times for me and go. I had the ability to spend a day recovering. (My symptoms were neither unusual for me nor outside the usual reported ones. But for me, I was not much good for about 24 hours after.)
I am aware that there are those with conditions who have been advised to wait. That plenty of people live in households with people currently unable to be vaccinated. Oh, and that worldwide the vaccine is only available in abundance in a handful of countries. Such that the worldwide vaccination rates are under 25 percent.
Someone got a lot of flack on Twitter earlier this year for pointing out that when working in international teams, it's worth considering that not everyone is in the same season. And sure, if someone wishes me a good morning, I don't yell at them to respect time zones. But I do often answer with, oh, good afternoon.
And one of the easiest things that people with access to vaccination can do, is remember that there are tons, literal tons of people, who still don't have the option yet.
