Should We Be Excited About the New Breast Cancer Vaccine?

This is an old story about some clinical trials long time ago. And but it still has relevance. What works for mice or dogs don't always translate to humans. Even a drug that could work to reduce a tumor by 50% may still just give you a few months till the tumor doubles again.

So the focus needs to be cure for the gravest ill metastatic patients NOW, the kind of drug that could reduce the tumor by 80+% and/or with progression free survival of 1+ years and/or response rate of >50% are going to be the winners for this war. Not the kind of drugs or vaccines for adjuvant uses or early stagers that will take 10 years to generate a decent data, which may or may not work, they are much more expensive to develop (paradoxically) and much less likely to work.
