India will expand its coronavirus vaccination programme today to cover people over 60 and those over 45 who have illnesses as it hopes to rein in a growing number of more infectious virus strains and a spurt in cases in some states. Registrations are set to open at 9 am at www.cowin.gov.in and the Aarogya Setu app and there will be walk-in vaccinations in some places as well. India began its vaccination drive on January 16 intending to inoculate 3 crore frontline workers but has struggled with hesitancy, giving out some 1.43 crore shots so far.
