The vaccination centres of the Calcutta Municipal Corporation resumed administering Covishield on Monday, after a gap of three days, with many queuing from early in the morning to ensure they did not miss out on the jab.

Hundreds of people from districts, who joined the queue relatively late, had to return without getting the jab because each vaccination centre of the civic body received only around 150 doses for the day.

The civic body had suspended administration of Covishield on Friday after running out of doses.

“We resumed administering Covishield on Monday following the arrival of fresh stocks. Adequate stocks arrived today, so the drive will continue at least for the next few days,” said a CMC doctor.

“Each primary health centre of the CMC will administer about 200 Covishield doses on Tuesday.”

Sagarika Mondal, 29, and her mother Jogamaya, 49, turned up outside the primary health centre of Ward 73, in Kalighat, at 6.30am. The residents of Sonarpur, on the southern fringes of the city, had left home at 5.30am.

Sagarika cycled and her mother took an autorickshaw to Mukundapur, from where they arrived at the health centre by bus.

“We had to travel this far because there are hardly any doses at the centres near home. We handed our documents to the local panchayat and they promised to let us know when doses would be available. Someone told us to try our luck in Calcutta because the centres here are better stocked,” said Sagarika.

The two left in the late afternoon after getting the shot.

Those who joined the queue at several centres after 8am could not get the jab as the doses had been exhausted by the time their turn came.

Outside many centres, the number of people in the queue was 1.5 times or even twice the number of doses the centres had received.

A health department official said they received 7.5 lakh doses of Covishield since Saturday, out of which about 80,000 were given to the CMC.
