Thanks for sharing that video with it. I'll see what it's about. I also agree that T-cells are much more important when it comes to coronavirus immunity as I've written about it before.

Here's a link in case you would like to see:

You also raised a good point about the long-term safety profile of a vaccine. While I'm no expert, at least I've not come across any convincing evidence that approved vaccines bring side effects in the long run (but let me know otherwise). From what I understand, vaccines train the immune cells for a while, and long-term immunity are actually conferred by the immune cells themselves (not the vaccines).

Regardless, many thanks for taking the time to write this long comment. :))
