Just hours after Haryana Health Minister Anil Vij, who was administered a dose of Covaxin last month, confirmed he has developed Coronavirus symptoms, the Union Health Ministry on Saturday clarified that Vij took only the first dose of the two-dose vaccine.

"The antibodies against the infection build up in a human being only after a specific number of days pass after the second dose of the vaccine is taken. This is a two-dose vaccine. Minister in question has taken only one dose of the vaccine," the ministry said in a statement.
