Perhaps you think that linking the swine flu vaccine with infertility is quite a stretch.  Well, let's take this one step at a time.

#1) Polysorbate 80 is in the Fluarix swine flu vaccine manufactured by GlaxoSmithKline according to the CDC.  This is confirmed by the CDC in the document below.....

#2) A medical study done in Slovakia injected newborn female rats with Tween 80 (Polysorbate 80).  These newborn female rats were injected with Polysorbate 80 at days 4 to 7 after birth.  The researchers found that Polysorbate 80 accelerated the maturation of the female rats, damaged the vagina and womb lining, caused significant hormonal changes, severe ovary deformities and ultimately rendered the young female rats infertile.

In fact, Dee Nicholson, the National Communications Director for Freedom in Canadian Health Care is not shy about saying that Polysorbate 80 is "linked to infertility in mice".
