There are all kinds of stories from people getting sick, not getting sick, whether or not they were wearing a mask or taking vitamins, or taking a vaccine. Sometime it seems there is not too much rhyme or reason.
Here is a very interesting case worth reading. Escape from Ecuador.
Bullet Points:
1. Was meticulous about mask-wearing and other prevention measures - still got COVID.
2. Was vaccinated - still got COVID (severe case).
3. Tried ivermectin and various other measures/supplements - didn't work.
Considering that this fellow was healthy (self-reported) vaccinated and still got a severe case, and that thousands of vaccinated people have already died from COVID, it makes me wonder about ADE. Since this guy had the J&J vaccine, I am unsure if ADE is as much of a possible issue as with the mRNA therapeutics.
Interesting that he got the vaccine - it didn't work - and yet he is planning to get a booster.
