Thanks to all for your replies and thanks to Becky for taking the time to expand the discussion further on vaccines.
Why I was particularly drawn to know more about this dendric cell vaccine was that it targets an onco-fetal antigen, not her 2, which I understand is present on cancer cells but not normal cells. I felt as it is targeted this specific abnormality i would only 'kill' the baddies not the 'goodies' therefore having a less destructive effect on other systems.If my memory of high school biology serves me right this onco- fetal antigen is present on foetuses up till about 20 weeks gestation to facilitate rapid growth and then it is 'turned off' genetically.How it appears on tumour cells I guess is unknown at present but seems to facilitate there rapid growth.
