A security guard who received the coronavirus vaccine at the All India Institute Of Medical Science (AIIMS), Delhi, on the first day of the immunisation drive, developed an allergic reaction and was admitted at the hospital, PTI reported.

AIIMS Director Randeep Guleria said the security guard, in his 20s, at AIIMS who received the jab after 4 pm, complained of palpitations and developed an allergic skin rash within 15-20 minutes after being inoculated and was admitted to the facility.

According to a PTI report, he had received a dose of Covaxin, India’s indigenous coronavirus vaccine, developed by Hyderabad-based Bharat Biotech. The clinical trial data for the vaccine hasn’t been released.

“He was immediately managed with appropriate treatment and he improved. He is stable,” Guleria said on Saturday.

“As a precautionary measure he has been admitted for overnight observation and his condition is being monitored. He is likely to be discharged in the morning,” the AIIMS Director had said.

One “severe” and 51 “minor” cases of AEFI (adverse events following immunisation) were reported among healthcare workers who were administered the coronavirus vaccine in Delhi on the first day of the COVID-19 vaccination drive on Saturday, official figures showed.
