Ryan, for your edification, here is a link
(WFS) to a discussion of this very subject on another forum. A lot of links, and well-informed answers and opinions. It is not hard data, but it is more ideas to consider, and use as a jumping-off point for further scientific research. After all, it is not like anyone so far has produced any hard data for you here (including myself)!
is a link to the Wikipedia page on vaccine controversies. I am not advocating you consider this to be the be-all, end-all of your research. But it does
overview of the arguments, as well as citations of studies you can read and then use as a jumping-off point for further research.
All I ask, is whatever choice you make please, please let it be a well-informed decision backed by serious medical research published in peer-reviewed scientific journals, not from just what anyone on the internet says. Again, including me.
