It IS the proper English word. Here’s the important part of the definition you posted:
administered primarily to prevent disease.

Why are people getting these shots? To prevent disease.

They’re vaccines.

I don’t give a damn if you get the vaccine. I don’t give a damn if you get ANY vaccine. I care about you LYING. When you say it’s not a vaccine that is a LIE.

The covid jab is literally a genetic engineering experiment that turns you into a genetically modified organism in an attempt to avoid an illness with a low probability of death for most people. So, I’ll call it a genetic engineering experiment. That’s true and accurate.

You call that a “vaccine.” Hey, you are free to use your language, though I disagree.

But in none of the above am I lying. So back off. Jack.

But they don't. Prevent disease, that is.

So now what, definition dude?
