Scientists at Harvard have developed a new cancer vaccine in pill form containing polymer disks saturated with tumor-specific antigens. In animal testing on mice, the magnetic nanodisc vaccines induced cancer cells to undergo apoptosis and led to remission and longer survival in many mice when implanted in the skin near tumors. However, the vaccine failed in human clinical trials.
