Union Health Minister Harsh Vardhan is in Chennai to review the second round of the Covid vaccination dry run today. The dry run will be held across 736 districts in the country. This comes after the first round was held on January 2. On the other hand, the flight operations between India and the United Kingdom resumed on Friday, after a suspension amid fears of a new Covid-19 strain. More than 250 passengers from the UK have landed in Delhi. The 256 passengers travelled to Delhi's Indira Gandhi International Airport from London's Heathrow Airport via an Air India flight on Friday morning.
