Herceptin Availability

I finished my AC +T and then 35 rads recently.
Where can I get Herceptin off trial?

Or does anyone know if there is a trial for node negative; er/pr neg; HER2+++ and no mets ?

I was told by my Med Onc that my "aggressive cancer" would benefit from Herceptin. Right now, I am looking at an expense of approx $76,000 for 1 year of Herceptin at a local oncologists office. My insurance is not wanting to cover the drugr, but will cover airfare! (go figure).

I keep reading about a vaccine on this site; but cannot find data explaining the vaccine... I hate to jump on board with all these questions, but would welcome any comments.

thank you- mts
