From across the table, he watched the scientific review committee grimly shaking their heads as his team member and longtime collaborator Lélia Delamarre made her case. Then he overheard the head of clinical development turn to the person sitting next to him and mutter, “Over my dead body. A vaccine will never work.”
That was in 2012. Cancer immunotherapy, which uses a person’s own immune system to attack tumors, is now one of medicine’s most promising fields, and one of the greatest breakthroughs in oncology in decades. But it took a long time to get there. Until the recent advent of a new class of blockbuster immunology drugs, the field was notorious for questionable science, hype, and spectacular disappointments.
And what Mellman and his team were proposing that day went further than turbocharging immune cells to make them better able to attack cancers. They were talking about a vaccine precisely tailored to…
