A medicinal product inducing immunity against disease, most often to prevent occurrence of a disease, (e.g., a preventative vaccine against infectious disease), but also to treat a disease, (e.g., a therapeutic vaccine against cancer). NOTE: The vaccines against infectious disease may contain various ingredients of diverse origin (such as inactivated or attenuated organisms, particular antigens related to the infectious agent, live recombinant vector against antigens in vivo and adjuvants) [After NCI Dictionary of Cancer Terms. After European Pharmacopoeia section 5.1.] See also treatment, prevention, prophylaxis, biological product.

A substance or group of substances meant to cause the immune system to respond to a tumor or to microorganisms, such as bacteria or viruses. A vaccine can help the body recognize and destroy cancer cells or microorganisms.

A Type of medicine that creates an immune protection without the recipient experiencing the disease.

Preparations containing substances with antigenic properties administered to activate the immune system, thereby inducing an immune response.

Prophylactic or therapeutic preparation given to produce immune response to pathogenic organisms or substances; vaccines are used not only in infectious disease prevention and treatment, but in neoplastic and autoimmune disease treatment, control of fertility, drug abuse control etc.

Suspensions of killed or attenuated microorganisms (bacteria, viruses, fungi, protozoa), antigenic proteins, synthetic constructs, or other bio-molecular derivatives, administered for the prevention, amelioration, or treatment of infectious and other diseases.

Vaccine, suspension of weakened, killed, or fragmented microorganisms or toxins or of antibodies or lymphocytes that is administered primarily to prevent disease. A vaccine can confer active immunity against a specific harmful agent by stimulating the immune system to attack the agent. Once...
