There has been a document circling around about the covid vaccine without a source. Title: "I have carefully studied..." And it has been spread via pastebin without knowing who said it.
I found the source:
The doc came from a comment from a Ben Swann video. https://youtu.be/xAQYzJxt8rE
The comment in question is from youtube channel: https://youtube.com/user/JarrodDSchneider

I've read about this before in various articles. The animals in the study received the vaccine and then died when they got the actual illness.
