After the false claim that Tylenol causes Autism, the many jokes making fun of that statement will eventually lead to a good amount of people at least subcontiously connecting Tylenol to autism

See for example many comments, including the top comment of this post: https://www.reddit.com/r/nextfuckinglevel/s/fDfhzwJhLE

These joke comments are probably meant as a sarcastic commentary about the ridiculous comments about Tylenol causing autism in a child when used during pregnancy. But this working as a joke is tied to the reader knowing that this false claim was made and the Tylenol comment is making fun of that.

I predict that if these comments continue in this way, the original context will eventually be lost in many cases and many people will see these jokes assuming they are somewhat serious and will actually believe that there is a connection between Tylenol and Autism.

Also seing these comments over and over again will subcontiously make people connect Tylenol to Austism even if they know the original context and know it's meant as a joke.
