Despite having reserved 70 per cent of vaccine stock for second doses, the public centres have ended up administering less than 40 per cent in the city. The decision of reserving vaccines was taken amid a high number of eligible people for a second dose in August.

As mass inoculation of people over 18 years of age started in May this year and considering that the gap of 84 days between two doses completed in the last week of July, the civic administration estimated a high demand for second doses in August. As per the estimation, more than 13 lakh people were eligible for a second dose between the last week of July and August 31. To handle this demand, the BMC planned to make available more vials for second doses.
