Union Health and Family Minister Dr Harsh Vardhan on Friday hailed India's decision to give nod to emergency authorisation for two Coronavirus vaccines. He praised the country's performance in developing vaccines at such a short span of time. "It would be a reality to vaccinate the entire population in the country against Covid-19 after prioritising risk groups," he said after reviewing the dry run of administering Covid-19 vaccine at the Rajiv Gandhi Government General Hospital in Chennai.
