For the fourth time in a fortnight, the civic body`s Covid-19 immunisation drive has been affected due to shortage of vaccine. It has been forced to close all public centres on Friday, twice since vaccination opened for all adult beneficiaries on June 21. Vaccination will resume once the fresh stock arrives, said a civic official.

The city has faced a shortage of the vaccine twice this week. On Tuesday, vaccination centres operated only for the second session due to late arrival of the fresh stock, which lasted only two days. On Thursday, only 16,112 doses were administered across centres, much lower than Wednesday`s figure of 58,311. Whereas, private centres have been consistently vaccinating an average of 30,000 beneficiaries daily.
