Precautionary doses are primarily to mitigate the severity of infection, hospitalisation, and death, the Centre's top medical research body said in a press conference today. The government also assured the people that there is no need to panic due to rising Covid cases as we are prepared for a surge. "All Covid vaccines, whether they are from India, Israel, US, Europe, UK, or China, are primarily disease-modifying. They don't prevent infection. The precautionary dose is primarily to mitigate the severity of infection, hospitalisation, and death," Dr Balram Bhargava, Director General of the Indian Council of Medical Research (ICMR) said.
