Yep, I witnessed it at the company I work for. And these employees that were fully vaxed had the same deadly symptoms that a first timer gets. Both of them got the transfusions even though vaxed. They weren't taking any chances. The aftermath was the very same symptoms that I had (breathing issues). It all cleared up for them just like it did for me.
My relative's who are over 80 just got over a severe respiratory virus, and it actually gave both of them the same symptoms that Covid gives. Took them around two weeks to get over it, and after that they felt weak, and was having trouble breathing for another week along with a cough that wanted to hang on.
Wasn't Covid though, and they are fully recovered now. I had a cold myself that lasted about a week and a half, but no COVID either, so hopefully we are seeing less and less of the Covid, and more and more of the normal viruses back again.
There was something going around, but it wasn't Covid thank goodness. Everyone is recovering well. Onward we all go.
