I'm not sure how any of this relates to vaccines, since we are talking about fluoride. But anytime you want to know if something is true or not, the only way I know of is to dig deeper for more information.
No, you're going to have to do the legwork of going to one of the many other pro-fluoridation sites to read those studies. Then, depending on how interested you are in the truth, you'll have to weigh all of the findings, and even look into who produced the studies (follow the money). Welcome to the 21st century, where it usually takes some effort to find the truth in controversial issues.
One thing to keep in mind while digging in, we know there is a financial incentive behind pro-fluoridation studies (it is expensive for business to dispose of it). As far as I know, there isn't much financial incentive in being against fluoridation, save for some boutique toothpaste brands that would probably lack the resources to conduct peer reviewed studies.
