Sullia : A daily-wage worker was vaccinated two doses of Covishield within minutes of each other at a crowded vaccination centre in Sullia taluk of Dakshina Kannada district on Wednesday.

The person he has been under observation though no adverse effect has been reported in the past 24 hours.

The incident took place at a school in the taluk’s Duggaladka village when the centre was chock-a-block with vaccine-seekers due to a mega drive conducted by the government on Wednesday.

KB Arun, from Kootelu village in Sullia, will still have to take another dose after a stipulated gap of 84 days.

Health officer Dr Nandakumar said the faux pas occurred when the man didn’t leave the room after taking the first dose, and the nurse on the job didn’t realise she was administering a second dose to the same person. “Soon after realising the mistake, he was made to remain under observation at the premises for 2-3 hours before he was sent home,” he said.

A team of health officers has been checking his vital parameters at his house since Wednesday evening.
