My comments have been misinterpreted: Adar Poonawalla clarifies on interview with UK media

In a Twitter post, Poonawalla, who left for London with his wife and children after being pressurised with threat calls in India, said: "I would like to clarify certain things since my comments may have been misinterpreted."

"First of all vaccine manufacturing is a specialised process, it is therefore not possible to ramp up production overnight. We also need to understand that the population of India is huge and to produce enough doses is not an easy task," he said.

"Even the most advanced countries and companies are struggling in relatively smaller populations," he added.

He also clarified that his company has been working closely with the government of India and that he has got all kinds of support-scientific, regulatory and financial.

In an interview with The Times London on Saturday, he spoke about the pressures he was under over the production of COVID-19 vaccines to meet the demand and also mentioned threatening calls from rich and powerful.

Poonawalla had said: “The level of expectation and aggression is really unprecedented. It’s overwhelming." SII is producing Covishield - the Oxford/AstraZeneca COVID-19 vaccine.

"I'm staying here (London) for an extended time because I don't want to go back to that situation. Everything falls on my shoulders but I can't do it alone...I don't want to be in a situation where you are just trying to do your job, and just because you can't supply the needs of X, Y or Z you really don't want to guess what they are going to do," Poonawalla had told the British newspaper.

Reports said under pressure he chose to fly into London to be with his wife and children. He has already been provided with 'Y'' category security by the Indian government.

"Everyone feels they should get the vaccine. They can't understand why anyone else should get it before them,"  Poonawalla had said.

The Serum India chief had also mentioned that he is meeting with the company's partners and stakeholders in the U.K. to set up a production base in the European country.

In his statement Monday, Poonawalla said the Serum Institute had supplied over 15 crore Covishield doses to the Centre since production began and had received an advance for another 11 crores.

An additional 11 crore doses, he said, would be delivered to states and private hospitals - in accordance with the centre's "liberalised" vaccination policy - within the next few months as well.

Poonawalla's statement comes as a part of an effort by the Centre and SII against media reports alleging that the government is yet to place fresh orders for COVID-19 vaccine doses.

"... media reports alleging the centre has not placed any fresh order for COVID-19 vaccines. The news reports suggest the last order... 100 million doses with SII and 20 million with Bharat Biotech... was in March 2021. These media reports are completely incorrect," the government said in a statement a few hours earlier.

The Serum Institute also responded with a tweet that said: "We endorse this statement & the authenticity of the information. We have been working closely with the Government of India for the past year & thank it for its support."
