TroVax or HER2 neu trial more effective for HER2neu?

[amccreery]

I am in the last steps of qualifying for the HER2 vaccine trial at UofW. They said I also qualify for the TroVax trial. I read on this forum that the TroVax vaccine targets four receptors versus the one that the HER2 vaccine targets. But the HER2 vaccine specifically targets HER2+positive cancers while the TroVax doesn't.

Does anyone know which is getting better results for HER2+ metastatic breast cancers?

Thank you.
