Queues at the NESCO jumbo centre swelled on Thursday. Vaccinations have been halted at several hospitals in Mumbai due to unavailability of doses. The Maharashtra government has complained of a shortage of vaccines, however, the Centre termed the complaints as "a deplorable attempt to divert attention from the failures of the state government and spread panic among people".
