[VIDEO] Here's a nice video on the immune system that might help you out. Their other videos on the immune system, the complement system, and viruses might also be helpful. Not the most technical deep dives, but good, abstracted explanations. In short, I don't think the vaccine prevents entry of the virus into the cells. That still happens, as it's a mechanical protein interaction (as far as I know). However, the vaccine (mRNA ones at least) work by producing the protein on the outside of the virus and putting that in your system, so your immune system learns how to respond. At least that's my mile-high interpretation.

You won't become a physicist from watching Carl Sagan's Cosmos , but I found it immensely educational. It's worth knowing what science knows about what the universe is and our place in it. Of course you aren't going to become an expert in astronomy, but you don't need to be. Many, certainly not all, but many of these videos are educational in the same sense. They give a layman a basic grasp of a complex subject. E.g. this video on the immune system won't make you a biologist, but it's still pretty informative: [VIDEO] These are the kinds of videos that teachers might show in a classroom. Certainly they are way better made than the cheesy, poorly made educational videos I saw in school. And to be fair, all of this stuff is entertainment, even Cosmos. There's no practical value to me to learn about how stars are made, or how the immune system works. But I find these things interesting.
