NEW YORK â How is the COVID-19 vaccineâs safety and efficacy ensured?
I volunteered for a trial of the Oxford-AstraZeneca vaccine and saw firsthand how scientists and doctors make sure that it is safe and effective before releasing it to everyone.
The Oxford University-developed vaccine made by Serum Institute of India under the brand name Covishield began to be distributed in India last month as a part of what could be the worldâs biggest vaccination program, and in dozens of countries on four continents.
It was already the mainstay of Britainâs anti-coronavirus drive.
I joined the trial conducted by the New York University Langone Vaccine Centre in New York City, where I am based as a U.S. correspondent for IANS, and received two trial injections.
