The Mumbai civic body has received bids for the supply of Pfizer, AstraZeneca and Sputnik in response to its global tender for one crore doses, a top official said today. Pfizer has refused to sell its vaccine directly to states and has told states like Punjab it will only deal with the central government. The Municipal Corporation of Greater Mumbai (MCGM) had floated global tenders to buy vaccines at Rs 700 crore on May 12.
