Vaccination of senior citizens began on a slow start at the BKC jumbo Covid-19 centre in Mumbai due to technical issues. The response to the citizen round, however, is encouraging said the facility at Mulund, the eastern suburb of Mumbai. While on-spot regsitrations began after 9am, actual vaccination could only begin after 11am because of a glitch. Officials are required to register details about allotment before administering doses and were unable to complete this process leading to delay. There was a one-hour delay in the morning but now the vaccination process is going on swiftly. By afternoon over 100 senior citizens and persons with co-morbidities registered for vaccines. We have capability to vaccinate upto 1,000 senior citizens a day in addition to medical personnel and other frontline workers, said Dr Rajesh Dere, dean of Covid centre at BKC.
