London - A vaccine has been developed to destroy cancer cells without damaging healthy ones.
When it infects a cell, the vaccine — a type that attacks rather than prevents disease — can produce thousands of copies of itself, which then spread to nearby cancer cells to kill them.
Developed by Oxford-based PsiOxus Therapeutics, the vaccine is in clinical trials for ovarian and colon cancers that have spread. Its developers say it represents a new generation of “self-amplifying” cancer therapies.
Though it has potent anti-cancer cell effects, the vaccine leaves healthy cells alone because it can’t over-ride their natural defences, a lab study suggests.
