To prevent vaccine theft, the government has added a security code: how it operates and other information
It would also reduce the risk of impersonation and unauthorised use of CoWIN's flexibilities for promoting vaccine coverage, according to the government. From May 8, 2021, the CoWIN framework will have a new "4 digit authentication code" option in the CoWIN programme. The protection code would guarantee that data entries about a citizen's vaccine status are documented properly, as well as reducing the risk of impersonation. You must have a copy of their appointment slip (digital or physical) and/or their registered cell phone with appointment confirmation SMS. After the vaccine has been done successfully, you can receive a confirmation SMS. If one does not get the confirmation SMS, one should get in touch with the vaccinator.
