That's up to what one considers normal in a given situation. I think I was quite clear about how I was using the word "normal" in my comment there. If I down a sixpack of beer, then I think most would agree that my blood alcohol content would be above normal, no matter how much that is to be expected. Yes, it would be normal for a person who just drank six beers, but not normal for humans as a whole. Oh and the amount of microplastics in both our brains might as well be considered "normal", given that the world is as fucked as it is.
Now, the argument can obviously made that being vaccinated is a lot more normalized than being drunk is, but since she's talking about the concept of vaccination as a whole, I think the current standards of normalcy are not what she's using. By the standards she might be argued to be using, it's a lot more normal to die of polio. In the history of our species, it's quite abnormal to be able to talk to people on the other side of the planet or to live past 60 or to get vaccinated.
I fully agree that the tweet is misinformation at best. I've just seen way too many of these fuckers weasel their way out on technicalities when confronted about it.
