IMO: As far as I can tell NIH does only invest in promising technology! :) NIH did their homework and did not just invest in a platform that is going to announce to fail in a few weeks from now MR Adam F.
BTW something ironic: AF is collecting funds for NIH and therefore for DCVAXL indirectly "I WANT TO RAISE $100,000 FOR CANCER RESEARCH thru my #PMC2017 bike ride." You go girl ;)
