Wow. A lot of “I don’t know” and heavy conjecture going on in this topic. Unfortunately, there is too much information from too many sources in too many countries on too many sites, including Facebook - if Facebook can be considered anything other than a digital human trap.
One must be very careful these days not to sound anti-c thingy. COVID-19(84) has divided people everywhere and are being censored for posting anything that is not accepted as “The Truth” according to politicians, Facebook, YouTube et al instead of scientists.
Nations, instead of coming together to unite against a common enemy (COVID) decided to bar each other from entering. The U.S. doesn’t need to build a wall now - it’s borders are boarded from four sides now. Russia and FSU claim to have been using vaccine effectively for awhile now. But we can’t trust them - can we. They might send us poison instead. Some of the world is moving forward with their vaccine. Others are waiting for ideas. It’s all very stupid IMO.

Don’t forget to wipe your phone. Now call 911 and report what you’ve just done.
But I won’t say it.
