Nitin Mishra, an emergency medical officer at the Civil hospital, had been vaccinated with Covaxin on February 15 and then on March 16. However, he developed a severe cough along with a mild fever on March 18 and got himself tested on March 20. The report on 21st March revealed that he was COVID-19 positive and has isolated himself at home because he has only mild symptoms and regularly monitors his blood pressure and blood oxygen levels. Subhash Chandra Sundariyal, director, Civil hospital, said that "We are also in touch with him and in case, symptoms aggravate, he will be hospitalized. The entire hospital has been sanitized and services are continuing as usual".

Meanwhile, the director-general of medical health, D.S. Negi confirmed that Nitin Mishra's case is the first recorded instance where a person has been found to have contracted COVID-19 and turned symptomatic after completion of the two-dose course of Covaxin. Negi said "Data shows that the efficacy of Covaxin is about 80-90 per cent. The vaccine does not act as a shield against infection, but protects a person from falling critically ill, hence people should go for the vaccine, if they are medically eligible, without any hesitation".

Professor Amita Jain, head of the microbiology department at King George's Medical University, said "It takes a few weeks, even after completion of the vaccination course, to build full immunity against the disease. During this period, a person may get infected and develop symptoms".
