Wow, and research conducted at such a prestigious research institute. Let's take a look at it. I bet the lab is behind the hammock.
Now let's take a look at it's primary sponsor. Oh...Joseph Mercola's funded NVIC. I'm sure that has nothing to do with him selling vitamin supplements that are pitched as the healthy alternative to vaccinations.
Now the storied publication that printed and peer-reviewed the paper. Started in 2020, not available in either NIH peer-review index, most of the first "peer-reviewed" papers focused on much-debunked COVID pseudo-science, its editors and "peers" are well known quacks including Peter A. McCullogh and Aseem Malhotra.
Now let's look at the most obvious question associated with this type of study that looks at billing codes and not actual medical records. When comparing the data, did they check to see if the NDD diagnosis came before or after the vaccinations...oh, no they didn't. Do they know what vaccinations the kids had received prior to a NDD diagnosis if in fact came after the vaccinations...oh, no they don't know that either.
