Essential changes have now been made on the Co-WIN digital portal, making online or on-site appointments for the Covishield vaccine not possible if the period after the first dose for a beneficiary is smaller than 84 days, it was announced on Sunday. Source- India TV. Union Health Ministry's Statement The Union Health Ministry said, "Cowin digital portal has been reconfigured to reflect the change in dose interval of Covishield vaccine to 12-16 weeks." What about already booked slots? Already booked online appointments for the second dose of Covishield will remain credible and are not being canceled by Cowin. But they advised the beneficiaries to reschedule their appointments for a later date after the 84th day from the first dose of vaccination. The Central government has restated to the states and UTs that the online appointments made for the second dose of Covishield before this change of the interval between the two doses, must be respected, and field staff notified that, if such beneficiaries come for vaccination, the second Covishield dose must be administered and the beneficiaries must not be turned off. They have also been urged to undertake awareness activities to inform the beneficiaries about this change. The Covid Working Group chaired by Dr. NK. Arora had recommended the expansion of the gap between the first and second doses of the Covishield vaccine to 12-16 weeks.
