“Issues like vaccine security, cost, equity, cold-chain requirements, production timelines etc., are also been discussed intensely," he stated.
On the availability of the vaccine and its authorization, Vardhan informed that Centre is considering emergency authorization of COVID-19 vaccination especially in the case of senior citizens and people working in high-risk settings. “This shall be done after a consensus has been reached", he said, according to an official statement.
To allay fears regarding the safety aspect of the vaccines, he said, "I shall be the first to offer myself for receiving COVID vaccine, if people have a trust deficit."
He also noted that a safe and effective vaccine will help in establishing immunity to COVID-19 at much faster pace as compared to the natural infection. It is hoped that a consensus will emerge in next few months over the desired level of protective herd immunity in any community, he stated.
Elaborating on the vaccine candidates and their development in India, Vardhan added that Department of Bio Technology (DBT) as well as Indian Council of Medical Research (ICMR) have been pro-active in responding to the emerging situation to support advancement of vaccine candidates.

Currently, India has three vaccine candidates, including country's first indigenous vaccine candidate Covaxin, which are in different phases of the clinical study, top ICMR scientist (Prof) Balram Bhargava informed earlier. "So at the present moment, we have three Indian vaccine candidates which are in different phases of a clinical study. Studies for Phase 1 and 2 are to determine the safety and very early efficacy."
The Covid-19 vaccine candidate Covaxin, developed by ICMR and Bharat Biotech, is currently in Phase I/II human trials and is being tested at 12 institutes across India.
For the vaccine candidate developed by AstraZeneca and Oxford University, pharma major Serum Institute of India (SII) said it will resume the trials in India once Drugs Controller General of India (DCGI) gives it requisite permission.
