Covid-19 Vaccine India: The time difference between the two doses of the Corona vaccine COVISHIELD has been increased. The Indian government said on Monday that given the emerging scientific evidence, the National Technical Advisory Group on Immunization (NTAGI) at intervals between two doses of a COVID-19 Vaccine Covishield (COVISHIELD) and then the National on Vaccine Administration of COVID-19 Expert Group (NEGVAC) has reconsidered. After this, the second dose of Kovishield has been suggested to be applied at an interval of 4-8 weeks after the first dose. Earlier this interval was 4-6 weeks. The revised timing decision between the two doses will only apply to Kovishield, not to Kovaxin.
