Sounds like they don’t understand that the vaccinated spread Covid.
Not very up to date or knowledgeable.
They do understand that vaccinated spread Covid. When they want them to. However, they do not want the sheep to know they understand what is going on. So they play the game and the sheep are none the wiser. Whether one gets Covid depends on whether they want them to get Covid at that time. If they want you to get Covid, you got it. If they don’t want you to get Covid, you do not have it.
