New Delhi, May 16 : Former Union minister and senior Congress leader P. Chidambaram on Sunday questioned the Narendra Modi government on the decline in the numbers of daily vaccination while taking a jibe at Health Minister Harsh Vardhan over the shortage of vaccines. "Why is the number of vaccinations administered going down every day? It was only 11,60,000 doses on Friday, bringing down significantly the daily average of May. It is a far cry from the 42 lakh doses administered on April 2. "The only reason and explanation is shortage of vaccines. Of course, the loyal and obedient Union Health Minister will flatly deny any shortage of vaccines!" Chidambaram said. Harsh Vardhan on Saturday reviewed public health response to Covid-19 and progress of vaccination in Uttar Pradesh, Madhya Pradesh, Andhra Pradesh and Gujarat. All the state health administrators were advised to increase ICU and oxygenated beds, undertake oxygen audits, take stock of availability of medicines in the state and strengthen their medical workforce. Detailing the ramping up of vaccine production, he said, "We will have 51.6 crore vaccine doses by the end of July including the 18 crore doses already administered. Sputnik has been approved. This along with the slated approval of the new vaccine of Zydus Cadila, Serum Institute of India- Novavax vaccine, Bharat Biotech's nasal vaccine and the Genova mRNA vaccine will push the availability of Covid vaccines to 216 crore doses in the August-December period." /IANS
