Indian biotech moment: A made-in-India Zika virus vaccine

The Zika virus vaccine developed by Bharat Biotech International Limited, Hyderabad goes well beyond the prime minister's catchy slogans as it is truly a 'made in India' by Indians moment and the patent on the product is also Indian.

The unbelievable story of the Zika virus vaccine breakthrough actually begins in 1996 with the remarkable tale of a middle class Tamilian farmer's son who trained to be a molecular biologist at the University of Wisconsin-Madison in USA deciding to come back to India. Krishna Ella, now the chairman-cum-managing director of Bharat Biotech was then egged by his mother to return to his motherland from USA.

Ella recalls his mother saying, "Son, you only have a 9-inch stomach and how much ever money you make, you can't eat more than that. You come back and do whenever you want, I will see to it that you get food! As long as I am alive, you will not starve."

Then 'start-ups' were not sexy, yet Ella took the risks and today he commands a USD 100 million company that specialises in vaccine production.

Having mastered the making of the world's cheapest hepatitis-B vaccine and the bulk supply of the oral polio vaccine of which Ella says he has supplied 3.5 billion doses among several other vaccines. Ella's company also partnered with Indian government to make the first-ever Indian-made vaccine called 'Rotavac', a vaccine against an infectious diarrhoea disease caused by Rota virus that afflicts children.

Ella being a scientist himself invests a lot in research and development and that is probably what led him start work developing vaccines against Japanese Encephalitis (JE) and Chikungunya both viral diseases that are mosquito borne.
