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
Sabin Vaccine Institute contribution to the field of vaccinology or related fields. The award is given in honor of the work of Albert B. Sabin. Past recipients of the award include Samuel L. Katz (2003), Joseph L. Melnick (1996), and Ruth S. Nussenzweig (2008). Sabin Vaccine Institute Sabin Vaccine Institute (Sabin), located in Washington, D.C., is a nonprofit (501(c)(3)) organization promoting global vaccine development, availability, and use. Through its work, Sabin hopes to reduce human suffering by preventing the spread of vaccine-preventable, communicable disease in humans through herd immunity, and also hopes to mitigate the poverty caused by these diseases.
