Anti-cancer vaccines emerging
Long envisioned drugs to harness the immune system could reshape treatments
For more than a century, doctors and patients have dreamed of using the body’s own defenses to fight cancer. Why, they wondered, can’t the immune system - so good at tracking down and destroying intruders - attack the tumor cells that invade healthy tissue? Finally, science is catching up with this vision. Just reaching the market in a big way, so-called therapeutic vaccines turn a patient’s immune system against the cancer that is growing inside them.
