Hmmm I wonder if it's because of the livelyhood's or due to the culture's where the many exposure's to the many viruses of a variety in nature are more prevalent, otherwise did the African's already have more of a built up immunity towards such a thing as opposed to the more civilized world ???
I go back to the India landfill analogy, where as you have people who live in landfills scavaging, and when the reporter came he had to mask up with PPE in order to survive the story being reported on at the landfill when came to do his report...
Was it because his immunity was severely weaker against the many things lurking in the landfill that the others had built up a natural immunity towards ??
Natural immunity is the best, but preventive shot's or safety measures can also help those who have had less exposure to the thing's that they aren't so sure about, and otherwise that could possibly kill them if exposed.
Now the feds not taking into consideration natural immunity, is what has created a nightmare in this country over the virus, otherwise it used the ignorant leftist cult mentality in which blanket's everyone, because leftist are just stupid when it comes to science, and are more driven by agenda's and unproven ideologies. The left is driven by the need to have everyone put on the same level regardless of the science, because it is forever thinking that they are being discriminated against or are being looked down upon or they are programmed to be scared of their own shadows thus making them perfect for becoming blind sheep for those who use them in that way.
