However, State health department officials stress on administering Covaxin for the second dose as those who got Covaxin first dose are still waiting for the second. “Since more people are waiting for Covaxin second dose, we have instructed centres to save Covaxin for them. In case any vaccination centre provides first dose of Covaxin, we will ensure that it is discontinued,” said Dr T S Selvavinayagam, director of Public Health and Preventive Medicine.
