The government today dismissed rumours that the Co-WIN app for self-registration of coronavirus vaccine beneficiaries will be made available this month for citizens above 50. The 50-plus category is the third population priority group after healthcare workers and frontline workers who are being administered the vaccines at present. Union Health Minister Dr Harsh Vardhan on Monday had said that the centre will be in a situation to administer vaccines against coronavirus to those above 50 years of age in March.
