Reaction to Vaccine Shot Not Necessarily Bad

Administration of coronavirus vaccine started in Delhi at 81 centres across the city on Saturday. Each Centre was targeted to administer vaccines to 100 people (health workers). Against a target of 8,117 health workers to be vaccinated on the first day of the drive in 11 districts of Delhi, a total of 4,319 were administered the vaccine, figures showed.
