New Delhi: In view of complaints by several users that they received notification of vaccination dose administered to them irrespective of missing their appointments made on CoWIN, the Union Health Ministry has introduced a new 4-digit security code feature in the CoWIN portal.
The ''4 digit security code'' to minimise errors for online bookings/appointments is operational from May 8.The step was taken after it came to notice that some citizens, who had booked their appointment for COVID-19 vaccination through the CoWIN portal but did not actually go for vaccination on the scheduled date, received SMS notification saying that a vaccine dose has been administered to them.
