Dendritic cell vaccination

Have just watched most of Ty Bollinger's 'The Truth About Cancer' and learned about dendritic cell therapy.  Has anyone done this?  How are you now?  I don't know if this is good for MM or not.   Your own cells are used to make a vaccine that wakes up the T-cells to destroy the cancer cells or other abnormal cells.  Normal cells are not destroyed so the immune system is not compromised.  Would love to hear about more therapies as well.
