The same approach is now being used to create a vaccine for the new coronavirus and she says she's "80% sure" it will work.
He said Prime Minister Narendra Modi's office was very closely involved in the vaccine production and the company is hoping the government will help foot the cost of making it.
However, Serum is not the only Indian company that is working on vaccine for coronavirus.
Paradoxically, the growing success of efforts to contain the spread of COVID-19, the disease caused by the virus, may present yet another hurdle.
An Oxford University vaccine for COVID-19 funded by the Coalition for Epidemic Preparedness Innovations (CEPI) last month has officially advanced into Phase 1 testing, complete with human trials.
Because of that confidence, Britain has begun allocating funds for large-scale development, a move that is financially risky if the vaccine turns out to be ineffective. "That's why we said we will go with this and that's why we are confident", Poonawalla told Reuters in a phone interview. The third step is conducting clinical trials, using volunteers in order to test the vaccine, and the fourth is to "begin the second round of clinical trials in larger populations of people who are at risk for infection", as stated on the Henry Ford Health System website. The monkeys were exposed to heavy quantities of the coronavirus, an amount that had previously sickened other monkeys in the lab, before receiving a single dose of the vaccine.

The government has said 40 per cent - or some 10 million people - would be needed for contact-tracing to be most successful. But privacy experts say there needs to be more transparency about the development of the app to ensure public support.
So how does the vaccine work?The vaccine is made from a weakened version of a common cold virus (known as an adenovirus) from chimpanzees that were modified so it can't rise in humans.
Donors are now spending tens of millions of dollars to start the manufacturing process at facilities in Britain and the Netherlands even before the vaccine is proven to work, said Sandy Douglas, 37, a doctor at Oxford overseeing vaccine production. Clinical trials of that vaccine are promising.
In the worldwide race for a vaccine to stop the coronavirus, the laboratory sprinting fastest is at Oxford University.
The Oxford group is also working with researchers in Kenya about a potential vaccine trial there, in which the rates of transmission are growing from a lower base.
The swabs are moving into human trials at SUNY Downstate Medical Center and Translational Genomics arch Institute (TGen), an affiliate of City of Hope, which should be completed by the end of next week, and are in preclinical evaluation at six additional hospitals.
The trial found that the macaque monkeys did not develop COVID 19 despite sustained exposure to the coronavirus and were found to be free of the virus even after 28 days.
