Aam Aadmi Party (AAP) MLA Atishi Tuesday said Delhi is left with only three days' stock of Covishield vaccine for the 18-44 age group, and if more doses are not supplied the vaccination drive for this category will have to be stopped in the city. Delhi's stock of Covaxin -- the second coronavirus vaccine in use in the country -- for this age group has already ended, leading the AAP government to shut vaccination centres administering the Bharat Biotech-made jabs to this category of beneficiaries.
