A plea by a 12-year-old on Monday urged the Delhi High Court to direct the Centre to provide a roadmap for vaccinating children 12 years and below against COVID-19. A bench of Chief Justice DN Patel and Justice Jyoti Singh said it would hear the plea on March 22. Tia Gupta (12) and a woman have submitted that presently vaccination is being administered to 15-17 age group and no roadmap is there to vaccinate children below 12 years of age.
