Polio vaccine is usually provided in vials containing 10–20 doses of vaccine. A single dose of oral polio vaccine (usually two drops) contains 1,000,000 infectious units of Sabin 1 (effective against PV1), 100,000 infectious units of the Sabin 2 strain, and 600,000 infectious units of Sabin 3. The vaccine contains small traces of antibiotics—neomycin and streptomycin—but does not contain preservatives. In a generic sense, vaccination works by priming the immune system with an 'immunogen'. Stimulating immune response, by use of an infectious agent, is known as immunization. The development of immunity to polio efficiently blocks person-to-person transmission of wild poliovirus, thereby protecting
Samuel Katz (pediatrician) the Albert B. Sabin Gold Medal awarded by the Sabin Vaccine Institute for his contributions to vaccine discoveries during his career. Samuel Katz (pediatrician) Samuel L. Katz (born 1927) is an American pediatrician and virologist whose career has been devoted to infectious disease research, focusing principally on vaccine research and development.
