While wealthy countries spent billions of dollars on vaccine development, they didn’t prepare for the 8-10 billion syringes needed for the Covid-19 vaccination effort. Enter Rajiv Nath, the managing director of Hindustan Syringes & Medical Devices, a company that is on the frontlines of the vaccination effort. Mr. Nath was contacted by UNICEF, the United Nations agency for children, about syringes it needed for vaccinating children last November. Nath was in a position to help because he and his company had been preparing their factories for the vaccination onslaught. The company added 500 workers to their production lines, which crank out more than 5,900 syringes per minute at factories in India. The company normally churns out 2.5 billion syringes a year, this year it will produce 3 billion by July.
