Covaxin, a home-grown Covid vaccine, will be administered to health-care workers from Wednesday at three medical colleges in the city, health officials said on Tuesday.

The three venues are the RG Kar Medical College and Hospital, Calcutta Medical College and Hospital and SSKM Hospital.

Covaxin shots will be administered at the same sites where doses of Covishield, the other Covid vaccine approved for emergency use in India, are being given.

Health department officials said the respective medical colleges would decide who would be administered Covaxin doses on Wednesday. A recipient has to sign a consent form.

Covaxin, unlike Covishield, is still undergoing phase III trial.

The consent form that the recipients of Covaxin need to sign mentions that the person receiving the vaccine has read the information sheet or has been told about it and he/she has understood the “benefits and risks of the vaccination”.

Metro has reported that the consent form does not mention that the data on the efficacy of the home-grown vaccine is still pending.
