Krishna Ella, 72, a yeast molecular biologist-turned entrepreneur, founded Bharat Biotech in 1994. The Hyderabad-based company grabbed headlines when it launched Revac-B, a recombinant Hepatitis-B vaccine, in October 1998. Priced at $1, it was the cheapest Hepatitis-B vaccine in the world at that time. The company later launched an oral polio vaccine (OPV). Despite limited resources, Ella was able pump Rs 1,000 crore into research through loans, grants and sale of shares . . .
The outcome was Rotavirus Vaccine (RV) against childhood diarrhoea, Typhoid Conjugate Vaccine (TCV), Japanese Encephalitis Vaccine, Influenza vaccine and a five-in-one Pentavalent vaccine.
