Vaccines

Preparations containing substances with antigenic properties administered to activate the immune system, thereby inducing an immune response. Vaccines range from inactivated or attenuated microorganisms (bacteria and viruses), enhanced autologous tumor cells, tumor antigens or epitopes that are used to elicit host immune responses. Vaccines are used for the prevention, amelioration, or treatment of infectious diseases and cancer. [from NCI]

Nicotine

A plant alkaloid, found in the tobacco plant, and addictive central nervous system (CNS) stimulant that causes either ganglionic stimulation in low doses or ganglionic blockage in high doses. Nicotine acts as an agonist at the nicotinic cholinergic receptors in the autonomic ganglia, at neuromuscular junctions, and in the adrenal medulla and the brain. Nicotine's CNS-stimulating activities may be mediated through the release of several neurotransmitters, including acetylcholine, beta-endorphin, dopamine, norepinephrine, serotonin, and ACTH. As a result, peripheral vasoconstriction, tachycardia, and elevated blood pressure may be observed with nicotine intake. This agent may also stimulate the chemoreceptor trigger zone, thereby inducing nausea and vomiting. [from NCI]
