Cancer vaccines work by stimulating the body's immune system to recognize and attack cancer cells.
There are two main types of cancer vaccines: preventive (prophylactic) vaccines and therapeutic vaccines.
Prophylactic cancer vaccines, like the HPV vaccine, prevent infections that can lead to cancer.
Therapeutic cancer vaccines aim to treat existing cancers by strengthening the body's natural defenses against the disease.
Common targets for cancer vaccines include tumor-associated antigens (TAAs) and neoantigens.
