Serum Institute of India's CEO Adar Poonawalla will get 'Y' category security across India by the Central Reserve Police Force, the Union government officials said on Wednesday.

The Union government's decision came after Director, Government and Regulatory Affairs at Pune-based Serum Institute of India, Prakash Kumar Singh had written to Union Home Minister Amit Shah on April 16 requesting security for Poonawalla.

Covishield, one of the two COVID-19 vaccines used in India's COVID-19 vaccination programme, is being manufactured by SII.

In this letter, Singh had stated that Poonawalla has been getting threats from various groups regarding the COVID-19 vaccine supplies.

In this letter, Singh also said, "we are working shoulder to shoulder to fight against COVID-19 pandemic with the Government of India under the dynamic leadership of Prime Minister Narendra Modi Ji."
