Nobody in the world should be denied the ability to access quality vaccines and preventive healthcare: that is the core of Poonawalla’s business philosophy. Today, her family-run Serum Institute of India—the world’s largest vaccine manufacturer by volume—is at the forefront of Covid-19 vaccine development and production. While husband Adar, chief executive of the company, is driving the initiatives, Poonawalla has been closely involved in expanding the company’s manufacturing facilities over the past few years, including a new 50-acre campus in Pune that is now being used to manufacture the Covid-19 vaccine. Having joined the business in 2005, in the early years Poonawalla worked with her husband to fill the shortage of vaccines for Rotavirus and Pneumococcal. Today the company produces 1.5 billion doses of vaccines a year which are used across 170 countries.
