Vaccination: People are waiting at Bhopal hospital in long queues to get a jab against Covid-19 , in Bhopal , Madhya Pradesh, India on May 27, 2021. The Ministry of Health and Family Welfare stated that making online appointments mandatory for inoculation for the 18-44 age group has so far prevented overcrowding at the vaccination centres.
