You're reading too much into this. It's irony, plain and simple

Leave it to the autist to ruin the joke 
I know...but it's used to make dumb people believe that masses of vaccinated people are not getting vaccinated, and then dying.

And that's absolute horseshit. It's fear-mongering, and it's totally wrong.
Unvaccinated people are fine. Oh wait! In Ontario, there are 56 unvaccinated people in the ICU per 1,000,000 unvaccinated people.
Oooh, I'm getting scared. LOL. Seriously, who gives a fuck?
I get your point though. You are right about this specific guy.
