The country has vaccinated 7,86,842 healthcare workers since the commencement of the nation-wide vaccination drive on January 16.

On Wednesday, 1,12,007 people were vaccinated across 20 states. Karnataka vaccinated 36,211 people, highest amongst all the states, followed by 22,548 in Andhra Pradesh and 16,261 in Maharashtra.

Besides this, Agnani said that a new feature of 'Allot beneficiary' in 'Ongoing session' has been added to the CoWin application to allow maximum possible number of beneficiaries per session and have better coverage.

The enhancement has also been done so that pre-registered beneficiary in the database can be added to the session as additional beneficiary over and above the scheduled number of beneficiaries.

Thirdly, the new feature will ensure that the person's name can be searched in the database by mobile number. Notably, provisional certificate will now be given after first dose and final certificate after second dose to every beneficiary.
