It's very frequently discussed.

The downvotes you're expecting are because this meme can be traced to a fraudulent claim in 1998: https://en.wikipedia.org/wiki/Lancet_MMR_autism_fraud

I declined the MMR vaccine at school because I was at school when that story came out, and at that point he and his claim were taken somewhat seriously.

(I did get the vaccine eventually).

That's the exact opposite of how it works. E.g. language acquisition in adulthood is much harder.
