Given a choice between sterility and ovarian cancer. I might pick plain old sterility.
If further studies confirm that association (the one discussed at your link), it means that some ovarian cancers could potentially be prevented by a vaccine that induces anti-MUC1 antibodies. Such a vaccine would be fairly straightforward to design, and the clinical trials would take a few years.
A quick perusal of PubMed reveals that various vaccines are being researched for the treatment of ovarian cancer. The MUC1 protein, in the aberrant form made by tumors, is a target of therapies currently under development.
And let’s not forget that the Big Gov agency touting these injections wants to eliminate the 2nd amendment: http://www.freerepublic.com/focus/f-news/3013757/posts
I just can’t help but question the validity of any of their claims and suggestions, vaccines, guns, or otherwise.
