I've read a lot of wild shit before but I've never come across a claim that Down Syndrome is caused by vaccines. Care to share the source of this information?

He won’t be able to provide a source, at least not a legitimate one. Down syndrome aside, no vaccine “modifies your DNA” despite many claiming the opposite. Whether that claim continues to propagate due to ignorance or malice is a different question.

I’m not even sure why GP brought it up, since the OP article has absolutely nothing to do with pharmaceuticals nor pharma companies.

I was looking forward to reading his illegitimate source.
