On Saturday, Vij tweeted, "I have been tested Corona positive. I am admitted in Civil Hospital Ambala Cantt. All those who have come in close contact to me are advised to get themselves tested for corona." According to reports, he participated in the trial on November 20.
At the moment, there is no way to determine whether the minister got the vaccine or the placebo shot.
Dr Shahid Jameel, senior virologist and director at Ashoka University explained that there were a couple of possibilities - one is that the minister is in a placebo group and since the trial is ongoing, the code cannot be broken to ascertain this. "Secondly, only one shot does not give sufficient immunity. He is not fully immunised as per protocol from phase 1 and phase 2 testing. Also, even after a full course of vaccination, some people can still get infected but the disease is mild," Dr Jameel said.
Covaxin is an indigenously developed Covid19 vaccine undergoing a trial on over 26,000 people across 25 sites in India to evaluate the efficacy of the vaccine candidate.
