Serum Institute of India Ltd. (www.seruminstitute.com) is the world’s largest producer of the Measles and DTP group of vaccines. Approximately two of every three children immunized globally are vaccinated by a vaccine manufactured by Serum Institute. Serum Institute’s products have been used in 140 countries. Serum Institute of India Ltd. was founded in 1966 by Dr. C.S. Poonawalla with the vision of manufacturing life-saving immunobiologicals in shortage in the country and imported at high prices. Thereafter, several life-saving biologicals were manufactured in abundance at prices affordable to the common man. Through Serum Institute, India was made self-sufficient for Tetanus Anti-toxin and Anti-snake Venom serum, followed by the DTP (Diphtheria, Tetanus and Pertussis) group of vaccines and later, for the MMR (Measles, Mumps and Rubella) group of vaccines. The Philanthropic philosophy of Serum Institute has been expanded to reduce the prices of newer vaccines such as Hepatitis-B vaccine, Rabies vaccine and Combination vaccine. Today, not only Indians, but all under-privileged children of the world in more than 140 countries are protected from birth onwards.
