Vaccines and HCG

[geocachingRN]

In response to a Tdap compliance letter I sent home, a parent really became upset and asked if I knew what was in the vaccine. That many contain HCG and would create problems for girls who wanted to become mothers later on. I assured her that it's her right not to have the vaccine but asked her for more info. Below are the sites I found but has anyone else had this come up?

beyond a few alarmist sites like those and one article that seemed to indicate that this was done as a clinical trial for those choosing to no longer have the ability to have children, I saw very little on this myself. The article I did see referred to Td in an adult population who were seeking sterilization techniques in lieu of tubal ligation. I see no hard evidence of any government plot to control the population by using tetorifice shots to setrilize school children - well, except for the rantings of the "Think twice" site over happenings in the Phillipines and Mexico - but again - they give no data or sources to back their claims up.
