The footfall for precautionary doses at vaccination centres in the city has seen a sharp drop, from around 10,000 daily doses at the beginning to around 3,000 now. Health officials have attributed the dip to the receding third wave.

The precautionary dose was introduced on January 10 after the strong demand, at least for healthcare and frontline workers, around the third week of December last year, when cases started increasing. On the first day, 10,698 healthcare and frontline workers took the jab and the figure remained steady till January-end with an average of 9,765 daily doses. However, the numbers started dwindling  after that.
