Depends on the vaccination whether or not the organism is dead. Some of them are 'modified live' which means they take a strain of the organism that's not virulent enough to cause disease and give it in very small doses. Some of them are genetic bits inserted into a canary pox virus carrier and given live. Some are whole dead or just parts of the original organism, given with an irritating adjunct to induce a bigger immune response.
The point of any vaccination is to cause an immune response, so that if your system encounters the organism you're vaccinating against, it'll have immune cells primed and ready to fight it.
So no vaccine should directly affect the nervous system. What your immune system does with its response may, in theory, affect a lot of things. Usually the worst that happens is that you have an allergic reaction (yay, aren't hives fun?), but when using modified live vaccines, it's possible to get a less severe variant of the disease, especially if you're stressed or immune-suppressed (this is why some people feel cruddy for several days after getting an influenza vaccine).
That said, there have been several studies that have found no causative link between autism and vaccines, and only one that ever did. That one has since been shown to have been picking up false positives, and the article I linked has links to a couple of papers that explain why those false positives were detected.
So the frustration is that the media will continue to run stories about the "great vaccine debate" and have any crackpot out there that can talk fast enough explaining in great detail how vaccines kill babies, because fear sells papers. While in actuality, there IS no "great vaccine debate" by anybody that knows anything about them. But THAT doesn't sell papers.
