Although our immune system is amazing at what it does, there are complex cases where the it fails us. Everyday, our bodies fight off hordes of bacteria and viruses that cause disease. When fighting cancer, our bodies even face their own cells that have gone rogue. However, certain pathogens and cancers manage to circumvent our immune system.
We talked to Dr. John Wherry, associate professor of microbiology and director of the Institute for Immunology at the University of Pennsylvania, about how the immune system is circumvented and what is being done about it.
