Preventive or prophylactic vaccines; Treatment or therapeutic vaccines; These vaccines are intended to treat existing cancer by stimulating the patient’s immune system. [3] Cancer vaccines can also divided into specific or universal cancer vaccine based on the types of cancer it is used for.
Tumor antigens have been a main target in specific active immunotherapy by way of vaccination. Tumor antigens are antigens produced by tumor cells and can be common among patients with the same cancer-type, or unique to a particular patient. Their specificity to malignant tumor cells makes tumor antigens ideal candidates for vaccination. [2]
mRNA-4157/V940 is an mRNA based cancer vaccine. When administered, it will produce one of several dozen possible abnormal proteins commonly found in cancerous tissues. The production of those proteins is intended to invoke an immune response. mRNA-4157/V940 is given to patients after their tumors have been sequenced and abnormal proteins ...
use of vaccines and other immunobiologic agents in clinical practice or preventive medicine; clinical or laboratory vaccine research; assessment of vaccine efficacy and safety; consumer perspectives and/or social and community aspects of immunization programs; at least one member must be an expert in this category.
The diagram above represents the process of chimeric antigen receptor T-cell therapy (CAR), this is a method of immunotherapy, which is a growing practice in the treatment of cancer. The final result should be a production of equipped T-cells that can recognize and fight the infected cancer cells in the body.
A cancer vaccine, or oncovaccine, is a vaccine that either treats existing cancer or prevents development of cancer. [1] Vaccines that treat existing cancer are known as therapeutic cancer vaccines or tumor antigen vaccines. Some of the vaccines are "autologous", being prepared from samples taken from the patient, and are specific to that patient.

In cancer vaccines, the goal is to generate an immune response to these antigens through a vaccine. Currently, only one vaccine ( sipuleucel-T for prostate cancer) has been approved. In cell-mediated therapies like CAR-T cell therapy, immune cells are extracted from the patient, genetically engineered to recognize tumor-specific antigens, and ...
