• A parliamentary panel on Friday informed the government of India that a vaccine for Covid-19 is expected only by early next year. Presentations were given by the Department of Science and Technology, Department of Biotechnology, Council of Scientific and Industrial Research (CSIR) and the principal scientific adviser to the government before the Parliamentary Standing Committee on Science and Technology, Environment and Climate on the Centre’s Covid-19 preparedness.
