Are vaccines immunological products?
Vaccines stimulate production of antibodies and other componenets of the immune mechanism. They consist of either: a live attenuated form of a virus (e.g. measles, mumps and rubella vaccine) or bacteria (e.g. BCG vaccine) or. inactivated preparations of the virus (e.g. influenza vaccine) or bacteria, or.
Which are the immunological products?

Toxoid vaccines (e.g. vaccines for diphtheria and tetanus) are made by purifying the bacterial exotoxin (Flow Chart 26.3). Toxicity of purified exotoxins is then suppressed or inactivated either by heat or with formaldehyde (while maintaining immunogenicity) to form toxoids.
