A attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or live). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. These vaccines contrast to those produced by killing the virus (inactivated vaccine).xamples of live (example attenuated) vaccines include: 1  Viral: measles vaccine, mumps vaccine, rubella vaccine, Live attenuated influenza vaccine (the seasonal flu nasal spray and the 2009 H1N1 flu nasal spray), chicken pox vaccine, oral polio vaccine (Sabin), rotavirus vaccine, and yellow fever vaccine.
Antigen vaccines. Antigen vaccines use specific proteins or parts of proteins (antigens) from the surface of cancer cells to stimulate the immune system to fight these cells. Cancer cell antigens are sometimes mixed with substances to help the vaccine work better.These substances are called adjuvants. vaccine stimulates the immune system to produce antibodies to fight a disease. Most vaccines are used to prevent infectious diseases caused by viruses, such as the flu, measles or polio. Cancer vaccines are used to: 1  prevent a cancer from developing (prophylactic, or preventive, vaccine).
